2.5.32 long-format changelog
Summary of changes from v2.5.31 to v2.5.32
============================================
<davidm@tiger.hpl.hp.com>
ia64: Sync up with 2.5.18.
<davidm@tiger.hpl.hp.com>
ia64: Fix fls() declaration so it actually gets inlined. Duh.
<eranian@hpl.hp.com>
[PATCH] Allow blocking on overflow notifications to work again.
<jenna.s.hall@intel.com>
[PATCH] Here is a small patch that missed inclusion with the bigger MCA logging
patch last February. Please include this in the next possible ia64 kernel
patch.
It fixes a bug in VA-->PA address translation when the kernel is not using
identity mapping (eg. Atlas discontig memory code) but the SAL still is.
<davidm@tiger.hpl.hp.com>
ia64: Add perfmon_itanium.h.
<davidm@tiger.hpl.hp.com>
ia64: Fix typo in arch/ia64/kernel/signal.c (reported by Peter Chubb).
<bjorn_helgaas@hp.com>
[PATCH] ia64: GENERIC build fixes.
<bjorn_helgaas@hp.com>
[PATCH] ia64: Here's a patch to make sba_iommu work again.
I added dma_address and dma_length to struct scatterlist and
removed orig_address. This brings IA64 in line with most other
architectures, but required a few changes to swiotlb.
Grant Grundler did the sba_iommu.c updates.
Note that this isn't *quite* enough to make the generic kernel
work on ZX1 boxes, because the ACPI in 2.5.18 barfs on a
ZX1 _CRS method.
David, I've tested both the swiotlb (on i2000 and ZX1) and
sba_iommu (on ZX1, with a kludge for the ACPI problem),
and they seem to work fine.
<davidm@tiger.hpl.hp.com>
ia64: Make gcc3.1 more aggressive with inline so it does the Right Thing on DRM.
<davidm@tiger.hpl.hp.com>
ia64: Wide IOSAPIC base_irq field to 32 bits. Patch by KOCHI Takayoshi.
<davidm@tiger.hpl.hp.com>
ia64: Get rid of obsolete MAP_NR_DENSE(). Patch by Bjorn Helgaas.
<davidm@tiger.hpl.hp.com>
ia64: Correct value delivered in siginfo.si_addr for SIGTRAP due to a debug
breakpoint. Patch by Stephane Eranian.
<davidm@tiger.hpl.hp.com>
ia64: Install NaT page at address zero to speed up speculation across
NULL pointers. Patch by Ken Chen.
<bjorn_helgaas@hp.com>
[PATCH] Here are a couple patches against 2.5.18-ia64-020530. The
first is some trivial cleanup in ia64/kernel/acpi.c (no need to
initialize automatics that are immediately assigned, don't
check for "0 == __va(x)", don't bail out of acpi_boot_init
on errors in MADT parsing (we might still be able to get
good stuff from SPCR, etc)).
The second applies on top of the first and cleans up legacy
keyboard detection by using the 8042 bit in the FADT boot
architecture flags. I think it's a little cleaner than the current
"#ifdef CONFIG_IA64" approach in pc_keyb.c.
<manik@cisco.com>
[PATCH] More__builtin_expect() cleanup in favour of likely/unlikely.
<davidm@tiger.hpl.hp.com>
ia64: Add McKinley-tuned versions of copy_user() and memcpy(). Patch by Ken Chen.
<davidm@tiger.hpl.hp.com>
ia64: Fix NaT consumption fault handler to not oops if fault was
triggered in a code section with an exception handler.
<davidm@tiger.hpl.hp.com>
ia64: Change EFI memory descriptor walking code to ignore memory
areas that could cause illegal memory attribute aliasing.
<davidm@tiger.hpl.hp.com>
ia64: Don't inherit all PSR bits across fork() & exec().
<davidm@tiger.hpl.hp.com>
ia64: Build memcpy.o on Itanium only.
<peterc@gelato.unsw.edu.au>
[PATCH] simserial.c needs hw_irq.h to get the declaration for ia64_alloc_irq().
<davidm@tiger.hpl.hp.com>
ia64: Fix perfmon initialization bug. Patch by Stephane Eranian.
<davidm@tiger.hpl.hp.com>
ia64: New file perfmon_mckinley.h.
<davidm@tiger.hpl.hp.com>
ia64: TLB flushing fixes and reserve large-page syscall numbers.
<kenneth.w.chen@intel.com>
[PATCH] This patch fixes some critical bugs in copy_user exception handler found by
Xavier. The fixes are all in the exception handler and there are no changes
in the main "copy" body. I have tested with both gcc2.96 and gcc3.1
compiler. Please report issues to me if there are any. Thanks.
<davidm@tiger.hpl.hp.com>
ia64: Misc. minor fixes.
<rusty@rustcorp.com.au>
[PATCH] Designated initializers for ia64
The old form of designated initializers are obsolete: we need to
replace them with the ISO C forms before 2.6. Gcc has always supported
both forms anyway.
<davidm@tiger.hpl.hp.com>
ia64: Fix formatting of Rusty's designated initializer changes.
<davidm@tiger.hpl.hp.com>

<steve.cameron@hp.com>
[PATCH] cpqfc, 2.5.30, lun fix
This is basically a port of a patch to 2.4 kernels to fix
the ioctls to pay attention to the lun field. For 2.5.30,
the passthrough ioctl is pretty broken, and this patch does not
fix that. (The patch I'm sending after this one does.)
-- steve
<steve.cameron@hp.com>
[PATCH] fix cpqfc passthrough ioctl for 2.5.30
This patch fixes the cpqfc passthrough ioctl for 2.5.30.
One question... Is it possible for a user app, by abusing
a upperlevel driver (e.g. the sg driver) to put a bogus
value into Scsi_Request->upper_level_private?
This patch kind of depends on this being impossible.
If it is possible, maybe it's better if I find another way
to identify passthrough commands on completion than what
this patch does. e.g. keep a list of the passthru Scsi_Requests
that are outstanding, then search the list on each completion...(yuck.)

[SCSI 53c700] clean up cli code
<greg@kroah.com>
USB storage: split up BUG_ON for easier debugging.
As requested by Adam Richter.
<david-b@pacbell.net>
[PATCH] ehci updates
This patch is the first part of fixing the EHCI driver to queue
interrupt transactions, handle larger requests, and basically treat
interrupt as just "bulk that lives on the periodic schedule". One
more patch should wrap that up.
qh processing cleanup
- split "append tds to qh" logic out of "put on async schedule",
so it can be used with "put on periodic schedule" too
interrupt transfer cleanup
- save rest of scheduling params in the qh
- calculate scheduling params only once
other cleanup
- use new container_of()
- minor code shrinkage (avoid pipe bitops, conditionals, etc)
- rename variable (will track endpoints, not urbs)
- free_config() logic
<hch@sb.bsdonline.org>
VM: Rework vmalloc code to support mapping of arbitray pages
The vmalloc operation is split into two pieces: allocate the backing
pages and map them into the kernel page tabels for virtually contingous
access. (Same for vfree). A new set of interfaces, vmap & vunmap does
only the second part and thus allows mapping arbitray pages into
kernel virtual memory.
The vmalloc.c internals have been completly overhauled to support this,
but the exported interfaces are unchanged.
<david-b@pacbell.net>
[PATCH] ohci, rm sparc64 oops
The recent "unlink cleanups" patch had a problem
with bitmask byteswapping.
<Andries.Brouwer@cwi.nl>
[PATCH] usb_string fix
Things are indeed as conjectured, and I can reproduce the situation
where usb_string() returns -EPIPE. Now that this is an internal
error code for the USB subsystem, and not meant to get out to the
user, I made these driverfs files empty in case of error.
(While if there is no error but the string has length 0,
the file will consist of a single '\n'.)
One fewer random memory corruption. Unfortunately, there are more.

[TRIVIAL] Use __cachline_aligned in netdevice.h
<ctindel@cup.hp.com>
drivers/net/bonding.c: Handle non-ETHTOOL devices more correctly.
<jsimmons@maxwell.earthlink.net>
Code cleanups and bug fixes.
<rusty@rustcorp.com.au>
[PATCH] ia64 incorrect field name in message
Fix module loader error message (from Keith Owens).
<david-b@pacbell.net>
[PATCH] ehci, debug info in driverfs
This patch teaches the ehci driver how to dump its schedule
through two driverfs files:
"sched-async" shows the control/bulk queue. usually has
no tds, often the idle queue head is showing.
"sched-periodic" shows the iso/interrupt schedule.
Since this is for debugging, the files aren't normally
configured into the driver.
<david-b@pacbell.net>
[PATCH] ehci does interrupt queuing
This patch makes EHCI
- Share the same TD queueing code for control, bulk,
and interrupt traffic;
- Queue interrupt transfers, modifying the code for
urb submit/unlink/complete;
- Thinner, by removing lots of nasty fatty special case
logic for interrupt transfers (size, no queueing, etc);
- Grow some "automagic resubmit" logic, ready to be
ripped out soonish;
- Package its interrupt scheduling so it can be called
from more places.
<david-b@pacbell.net>
[PATCH] expose dma_addr_t in urbs
This patch exposes DMA addresses in URBs. It exposes new APIs that
let drivers be a bit smarter in terms of DMA, reducing USB overhead
on some platforms (but not commodity pcs). As discussed with DaveM,
and on the usb-devel list.
Supporting patches are still needed. Of course, there's teaching HCDs
to use _these_ addresses when they're provided (easy). There's also
teaching drivers (like hid) to use the new usb_buffer_alloc() support,;
can happen incrementally. And adding scatterlist support, which will
be desirable for usb-storage and hpusbscanner. But this is the start
needed to get all of that going.
<acme@conectiva.com.br>
make psnap and p8022 use the new LLC stack
. kill BR_LLC_LOCK, not needed anymore
. kill net/core/ext8022.c, not needed anymore as all
UI 802.2 protocols now use the new LLC stack
. use struct list_head in datalink_proto (only needed by psnap)
. make IPX and Appletalk use datalink_proto->request
. make CONFIG_ATALK and CONFIG_IPX dependent on CONFIG_LLC
. fix __FUNCTION__ usage in LLC
<greg@kroah.com>
USB: Makefile fix for previous patch
<paulus@samba.org>
[PATCH] USB root hub polling and suspend
Currently with 2.5, when I suspend and resume my powerbook, I find
that the USB subsystem no longer sees root hub events, i.e. it doesn't
notice when I plug in a new USB device (it doesn't notice when I
unplug a device either but of course the driver for the device sees
that it is no longer responding).
It turns out that what happens is that the root hub timer goes off
after the OHCI driver has done its suspend stuff. The timer routine
sees that the HCD is not running at the moment and doesn't schedule
another timeout. Hence the series of timeouts stops.
<anton@samba.org>
ppc64: Remove -fsigned-char and use -mcpu=power4 in CFLAGS
<davem@nuts.ninka.net>

LLC: Remove global variables used in confirms and indications
. moved the global variables llc_ind_prim and llc_cfm_prim
to struct llc_sap, to make the code reentrant
. one kerneldoc comment for a struct
. created llc_pdu_{s,u}n_hdr and llc_set_pdu_hdr to abstract
access to skb internals (skb->nh.raw)
. renamed llc_get_llc_hdr_length to llc_get_hdr_len and simplify it
. killed some uneeded variables in llc_sap_send_ev

Change DEVICE_ATTR, BUS_ATTR, and DRIVER_ATTR macros to not take a '_str'
parameter, and just __stringify the name instead.
Update all the users of the macros.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Move calculating the currently used bandwidth
Calculate the currently used bandwidth only when we need it, not
continously in a timer handler.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Start cleaning isdn_net hangup timeout handling
The isdn network interface provides a number of ways to set up
automatic hangup after inactivity, and unfortunately consequently
rather mysterious code which handles that - at this point of cleanup
it's now possible to grasp what's going on.
<jsimmons@maxwell.earthlink.net>
Bug fixes for Sparc platform.
<patmans@us.ibm.com>
Hi -
Attached is cleanup/rewrite patch for scsi_scan.c against 2.5.30.
The only functional change is adding support for BFLAGS_LARGELUN,
it was defined before, but not used, otherwise the code should be
the functional equivalent of the pre-patch version.
The unused BFLAGS_NODISK was removed.
Tested with:
qla2300, v6 beta drivers modified for 2.5.x, with FCP switch attached
IBM 3542 (multi-LUN FC disk array, supports REPORT LUN)
SEAGATE ST118273 (FC disk drive)
serveRAID (ips driver, boot device)
AIC Adaptec 7896 with IBM-PSG ST318203LC (boot disk)
ISP1020 (qlogicisp driver) with Quantum DLT7000 tape drive attached

There's a bug for adapters with multiple channels (like the ServeRAID
with ips driver) not being properly scanned - it scans channel 0 again
rather than going to the next channel - patch on top of the original

[ATALK] fix compilation of appletalk drivers
The s/at_addr/atalk_addr/ in atalk.h broke the compilation of
drivers/net/appletalk/*. The patch below fixes it. From Adrian Bunk.
<mingo@elte.hu>
[PATCH] tls-2.5.31-D9
3 TLS entries, 9 cycles copying and no branches in the context-switch
path. The patch also adds Christoph's suggestion and renames
modify_ldt_ldt_s (yuck!) to user_desc.
<mochel@osdl.org>
Update device model locking
This updates the device model locking to use device_lock when accessing all
lists (the global list, the bus' lists and the drivers' lists). Before the latter
two would use their own rwlocks.
This also updates get_device() to return a pointer to the struct device if it
can successfully increment the reference count.
Between these two changes, this should prevent anything gaining an invalid
reference to a device that is in the process of being removed:
If a device is being removed, it's reference count is 0, but it hasn't
necessarily hasn't been removed from its bus's list. If the bus list iterator
attempts to access the device, it will take the lock, but will continue on to
the next device because the refcount is 0 (and drop the lock).
Well, theoretically; the bus iterators still need to be changed, but that's
coming next..

[PATCH] rmap bugfix, try_to_unmap
The following patch corrects a bug where rmap would continue trying to
swap out a page even after it failed on one pte, which could result in
leaked pte chains and a bug when exiting applications which use mlock().
The bug was tracked down by Christian Ehrhardt, the reason it wasn't
found earlier was a subtlety in the code, so I've taken the liberty of
changing Christian's patch into something more explicit, we shouldn't
let this one happen again ;)

[PATCH] Rearrange setting of snd/rcv buf size to avoid locking issue
Currently svc_sock_setbuf can be called under a spinlock,
but it can try to lock a socket, which can block....
Now when we decide that changing the size might be good we
set a flag (SK_CHNGBUF) and then later (when the next
packet arrives) we change the sizes appropriately.

[PATCH] PATCH - RPC/TCP 2 of 4 - Allow SO_REUSEADDR for NFS sockets
Otherwise if you cannot stop and restart nfsd while a client holds a

[PATCH] PATCH - RPC/TCP 3 of 4 - Correct error message when rpc/tcp sent fails
Now that we actually do shutdown the socket, we should
say so instead of just saying that we should....
<neilb@cse.unsw.edu.au>
[PATCH] PATCH - RPC/TCP 4 of 4 - Handle short read when reading RPC/TCP packet length
The code already copes with the possibility of having
read some of the 4byte length but not all, but can never
get into that situation. We just need to add a 'return'
for the case where read got some data but not enough.
Either 0 or -EAGAIN could be returned, they both have the
same effect.
<axboe@suse.de>
[PATCH] sym53c8xx_2
The following patch from Anton Blanchard fixes a problem with the
sym53c8xx_2 driver in the 2.5 tree. It assumes that the eh error
handlers are not called with the host lock held, which they are.

[PATCH] designated initializers for include/linux
These are the completely generic bits (linux/init_task.h and linux/wait.h).

Patches are against 2.5.31.
<rusty@rustcorp.com.au>
[PATCH] Designated initializers for i386
The old form of designated initializers are obsolete: we need to
replace them with the ISO C forms before 2.6. Gcc has always supported
both forms anyway.
<hch@lst.de>
[PATCH] i_sem-less generic_file_write for O_DIRECT & XFS
There are a number of places where generic_file_write could be used if
it didn't take i_sem by itself or where it doesn't need it:
(1) XFS needs to do some preparation in it's write file operation
(most notably taking it's own per-inode locks), after taking
i_sem, but before calling the guts of generic_file_write.
(2) blockdevices are happy with parralel get_block() operations,
and there is nothing i_sem could protect.
This patch introduces a generic_file_write_nolock and makes the good old
generic_file_write a wrapper around. The block device code is switched
over to it.
<hirofumi@mail.parknet.co.jp>
[PATCH] Fix generic_file_send()
sys_sendfile() call,
do_sendfile(out_fd, in_fd, &pos, count, MAX_NON_LFS);
in_file->f_op->sendfile(out_file, in_file, ppos, count);
But,
ssize_t generic_file_sendfile(struct file *in_file, struct file *out_file,

[PATCH] A generic RTC driver [1/3]
This is the current version of the genrtc driver from the m68k
community. This is slightly different than the version I have sent
previously in that it has been switched to C99-style initializers,
which was done in the current m68k CVS tree by Geert Uytterhoeven, and
the needed changes to select/compile it in general. I had previously
asked the m68k community if anyone objected to this being submitted by me,
and I got Richard Zidlicky's (who's at the top of the file) approval, as
well as Geert Uytterhoeven's approval.
<trini@kernel.crashing.org>
[PATCH] A generic RTC driver [2/3]
This is part 2 of 3 of the genrtc driver work. This is the PPC portion
of the patch, which creates include/asm-ppc/rtc.h. This has been in the
PPC bitkeeper tree for over a month now.
<trini@kernel.crashing.org>
[PATCH] A generic RTC driver [3/3]
This is part 3 of 3 of the genrtc patches. This is my own slight bit
of work, as well as some work by Randolph Chung. This changes
set_rtc_time(struct *rtc_time) to return an int instead of void.
This was done so that the arch-specific code here could do additional
checks on the time and return an error if needed. This then introduces
include/asm-generic/rtc.h, include/asm-i386/rtc.h and
include/asm-alpha/rtc.h. include/asm-generic/rtc.h contains the
get_rtc_time and set_rtc_time logic that is in drivers/char/rtc.c and
has been tested on SMP i386. This also modifies include/asm-ppc/rtc.h
to return -ENODEV if no rtc hardware is present.
Additionally, Dave Jones pointed out to me a place where we might not be
safe when jiffies wraps, so this switches that to time_after().
From Randolph Chung, support for a 64bit kernel and a 32bit userland.

[PATCH] get_cpu_var patch
This makes introduces get_cpu_var()/put_cpu_var() which gets a
per-cpu variable and disables preemption, and renames the (unsafe
under preemption) "this_cpu()" macro to __get_cpu_var(). It also
deletes the redundant definitions in linux/smp.h.
<rusty@rustcorp.com.au>
[PATCH] DECLARE_PER_CPU/DEFINE_PER_CPU patch
This old __per_cpu_data define wasn't enough if an arch wants to
use the gcc __thread prefix (thread local storage), which needs to
go *before* the type in the definition. So we have to go for a
DECLARE macro, and while we're there, separate DECLARE and DEFINE,
as definitions of per-cpu data cannot live in modules. This also
means that accidental direct references to per-cpu variables will
be caught at compile time.

Fix and prevent bugs in device_register()
When adding to the global device list, we were adding devices just after their parent, while we wanted to
add them just before. That way when we iterate over the list on suspend and shutdown, we'll hit all
children before the parents.
Make sure dev->driver_list and dev->bus_list are initialized when the device is registered
Remove device from global and parent's list if registration failed.

[PATCH] HCDs support new DMA APIs (part 1 of 2)
- teaches the hardware-specific code to
use urb->*_dma instead of creating mappings.
(And tells ohci-sa1111 to init its buffer pools.)
EHCI and UHCI also eliminated duplicated state;
all the HCDs are now a smidgeon smaller.
Sanity checked by enumerating, including through
a hub, and using a USB Ethernet adapter, with each
of the three host controllers.
Worth noting: this removes pci_dma_sync_single()
calls from UHCI. On x86 (and some others) that's
a NOP, but for UHCI on other platforms (rare except
maybe on IA64, as I understand) this anticipates
the upcoming patch to remove interrupt automagic.
(I'll likely submit that after a Linus release that
catches up to your USB tree. :)
<david-b@pacbell.net>
[PATCH] HCDs support new DMA APIs (part 2 of 2)
- teaches the shared "hcd" code to set urb->*_dma whenever the device

<mochel@osdl.org>
Update device model locking
Change all iterators of devices to:
- use list_for_each
- check return of get_device_locked
- don't break until we hold the lock if we get an error
When a device's reference count hits 0, remove it from all lists, including
bus and driver lists.
Between the iterator algorithm and the guaranteed removal from the lists,
there should never be a device in a list with a reference count of 0.
So, whenever we're iterating over the lists, we'll always have a valid
device. We don't decrement the refcount until the next iteration of the
loop, so we're also guaranteed to get the correct next item in the list.

[PATCH] Problem with CDC Ethernet driver (CDCEther.c)
- fixed deadlock
<akpm@zip.com.au>
[PATCH] fix ARCH_HAS_PREFETCH
include/linux/prefetch.h does a strange thing: if the arch doesn't have
the prefectch functions, this header defines no-op version of them and
then defines ARCH_HAS_PREFETCH. So there's no way for mainline code to
know if the architecture *really* has prefetch instructions.
This information loss is unfortunate. Examples:
for (i = 0; i < N; i++)
prefetch(foo[i]);
Problem is, if `prefetch' is a no-op, the compiler will still
generate an empty busy-wait loop. Which it must do. We need to
know the truth about ARCH_HAS_PREFETCH to correctly elide that loop.

[PATCH] random fixes
- I changed the sector_t thing in max_block to use davem's approach.
I agree with Anton, but making it explicit doesn't hurt.
- Remove a dead comment in copy_strings.
Old stuff:
- Remove the IO error warning in end_buffer_io_sync(). Failed READA
attempts trigger it.
- Emit a warning when an ext2 is mounting an ext3 filesystem.
We have had quite a few problem reports related to this, mainly
arising from initrd problems. And mount(8) tends to report the
fstype from /etc/fstab rather than reporting what has really
happened.
Fixes some bogosity which I added to max_block():
- `size' doesn't need to be sector_t
- `retval' should not be initialised to "~0UL" because that is
0x00000000ffffffff with 64-bit sector_t.
- Allocate task_structs with GFP_KERNEL, as discussed.
- Convert the EXPORT_SYMBOL for generic_file_direct_IO() to
EXPORT_SYMBOL_GPL. That was only exported as a practicality for the
raw driver.
- Make the loop thread run balance_dirty_pages() after dirtying the
backing file. So it will perform writeback of the backing file when
dirty memory levels are high. Export balance_dirty_pages to GPL
modules for this.
This makes loop work a lot better - I suspect it broke when callers
of balance_dirty_pages() started writing back only their own queue.
There are many page allocation failures under heavy loop writeout.
Coming from blk_queue_bounce()'s allocation from the page_pool
mempool. So...
- Disable page allocation warnings around the initial atomic
allocation attempt in mempool_alloc() - the one where __GFP_WAIT and
__GFP_IO were turned off. That one can easily fail.
- Add some commentary in block_write_full_page()

This patch that adds a prctl so that processes can set their

the exception mode setting interacts with the lazy FPU save/restore
that the kernel does.

Here is an update for scsi_debug that utilizes driverfs
support for per driver parameters added in lk 2.5.31
1.62 changes:
- driverfs support for these options (more to come):
/driverfs/bus/scsi/drivers/scsi_debug/delay [rw]
/driverfs/bus/scsi/drivers/scsi_debug/num_devs [r]
/driverfs/bus/scsi/drivers/scsi_debug/opts [rw]
- start using some C99
- fdisk requires EINVAL from unsupported ioctls
(scsi_debug previously used ENOTTY)
1.61 changes:
- simulate delayed responses, controlled by
'scsi_debug_delay'
- support REPORT LUNS
- support more MODE SENSE pages
- [following Doug Ledford's suggestion] do autosense
(i.e. set Scsi_Cmnd::sense_buffer array appropriately
when a status of CHECK CONDITION is set)

This version of sg for the lk 2.5 series re-adds direct IO
support using work done by Kai Makisara (on st driver, posted
2002/7/29).
Changelog:
Changes since 3.5.26 (20020708)
- re-add direct IO using Kai Makisara's work
- re-tab to 8, start using C99-isms
- simplify memory management
Like Kai's patch, this one needs kernel/ksyms.c altered
to export get_user_pages(). Kai's worker routines
st_map_user_pages() and st_unmap_user_pages() are duplicated
as is. Hopefully these routines will find a home in
a library soon.
The re-tabbing makes the patches rather large so here
are 2 urls:
This tarball contains sg.h and sg.c
http://www.torque.net/sg/p/sg3527.tgz
This gzipped patch is against lk 2.5.31 and touches
kernel/ksyms.c as well
http://www.torque.net/sg/p/sg_3527_lk2531.diff.gz
Testing is ongoing, everything works apart from "zero
copy" copy. That uses mmap-ed IO on the read side and
direct IO on the write side. Not too many people would
be using that I suspect.

[PATCH] lockd shouldn't call posix_unblock_lock here

<akpm@zip.com.au>
[PATCH] pagevec infrastructure
This is the first patch in a series of eight which address
pagemap_lru_lock contention, and which simplify the VM locking
hierarchy.
Most testing has been done with all eight patches applied, so it would
be best not to cherrypick, please.
The workload which was optimised was: 4x500MHz PIII CPUs, mem=512m, six
disks, six filesystems, six processes each flat-out writing a large
file onto one of the disks. ie: heavy page replacement load.
The frequency with which pagemap_lru_lock is taken is reduced by 90%.
Lockmeter claims that pagemap_lru_lock contention on the 4-way has been
reduced by 98%. Total amount of system time lost to lock spinning went
from 2.5% to 0.85%.
Anton ran a similar test on 8-way PPC, the reduction in system time was
around 25%, and the reduction in time spent playing with
pagemap_lru_lock was 80%.
http://samba.org/~anton/linux/2.5.30/standard/
versus
http://samba.org/~anton/linux/2.5.30/akpm/
Throughput changes on uniprocessor are modest: a 1% speedup with this
workload due to shortened code paths and improved cache locality.
The patches do two main things:
1: In almost all places where the kernel was doing something with
lots of pages one-at-a-time, convert the code to do the same thing
sixteen-pages-at-a-time. Take the lock once rather than sixteen
times. Take the lock for the minimum possible time.
2: Multithread the pagecache reclaim function: don't hold
pagemap_lru_lock while reclaiming pagecache pages. That function
was massively expensive.
One fallout from this work is that we never take any other locks while
holding pagemap_lru_lock. So this lock conceptually disappears from
the VM locking hierarchy.
So. This is all basically a code tweak to improve kernel scalability.
It does it by optimising the existing design, rather than by redesign.
There is little conceptual change to how the VM works.
This is as far as I can tweak it. It seems that the results are now
acceptable on SMP. But things are still bad on NUMA. It is expected
that the per-zone LRU and per-zone LRU lock patches will fix NUMA as
well, but that has yet to be tested.
This first patch introduces `struct pagevec', which is the basic unit
of batched work. It is simply:
struct pagevec {
unsigned nr;
struct page *pages[16];
};
pagevecs are used in the following patches to get the VM away from
page-at-a-time operations.
This patch includes all the pagevec library functions which are used in
later patches.
<akpm@zip.com.au>
[PATCH] multithread page reclaim
This patch multithreads the main page reclaim function, shrink_cache().
This function used to run under pagemap_lru_lock. Instead, we grab
that lock, put 32 pages from the LRU into a private list, drop the
pagemap_lru_lock and then proceed to attempt to free those pages.
Any pages which were succesfully reclaimed are batch-freed. Pages
which were not reclaimed are re-added to the LRU.
This patch reduces pagemap_lru_lock contention on the 4-way by a factor
of thirty.
The shrink_cache() code has been simplified somewhat.
refill_inactive() was being called too often - often just to process
two or three pages. Fiddled with that so it processes pages at the
same rate, but works on 32 pages at a time.
Added a couple of mark_page_accessed() calls into mm/memory.c from 2.4.
They seem appropriate.
Change the shrink_caches() logic so that it will still trickle through
the active list (via refill_inactive) even if the inactive list is much
larger than the active list.
<akpm@zip.com.au>
[PATCH] batched movement of lru pages in writeback
Makes mpage_writepages() move pages around on the LRU sixteen-at-a-time
rather than one-at-a-time.
<akpm@zip.com.au>
[PATCH] batched addition of pages to the LRU
The patch goes through the various places which were calling
lru_cache_add() against bulk pages and batches them up.
Also. This whole patch series improves the behaviour of the system
under heavy writeback load. There is a reduction in page allocation
failures, some reduction in loss of interactivity due to page
allocators getting stuck on writeback from the VM. (This is still bad
though).
I think it's due to the change here in mpage_writepages(). That
function was originally unconditionally refiling written-back pages to
the head of the inactive list. The theory being that they should be
moved out of the way of page allocators, who would end up waiting on
them.
It appears that this simply had the effect of pushing dirty, unwritten
data closer to the tail of the inactive list, making things worse.
So instead, if the caller is (typically) balance_dirty_pages() then
leave the pages where they are on the LRU.
If the caller is PF_MEMALLOC then the pages *have* to be refiled. This
is because VM writeback is clustered along mapping->dirty_pages, and
it's almost certain that the pages which are being written are near the
tail of the LRU. If they were left there, page allocators would block
on them too soon. It would effectively become a synchronous write.
<akpm@zip.com.au>
[PATCH] batched removal of pages from the LRU
Convert all the bulk callers of lru_cache_del() to use the batched
pagevec_lru_del() function.
Change truncate_complete_page() to not delete the page from the LRU.
Do it in page_cache_release() instead. (This reintroduces the problem
with final-release-from-interrupt. THat gets fixed further on).
This patch changes the truncate locking somewhat. The removal from the
LRU now happens _after_ the page has been removed from the
address_space and has been unlocked. So there is now a window where
the shrink_cache code can discover the to-be-freed page via the LRU
list. But that's OK - the page is clean, its buffers (if any) are
clean. It's not attached to any mapping.
<akpm@zip.com.au>
[PATCH] make pagemap_lru_lock irq-safe
It is expensive for a CPU to take an interrupt while holding the page
LRU lock, because other CPUs will pile up on the lock while the
interrupt runs.
Disabling interrupts while holding the lock reduces contention by an
additional 30% on 4-way. This is when the only source of interrupts is
disk completion. The improvement will be higher with more CPUs and it
will be higher if there is networking happening.
The maximum hold time of this lock is 17 microseconds on 500 MHx PIII,
which is well inside the kernel's maximum interrupt latency (which was
100 usecs when I last looked, a year ago).
This optimisation is not needed on uniprocessor, but the patch disables
IRQs while holding pagemap_lru_lock anyway, so it becomes an irq-safe
spinlock, and pages can be moved from the LRU in interrupt context.
pagemap_lru_lock has been renamed to _pagemap_lru_lock to pick up any
missed uses, and to reliably break any out-of-tree patches which may be
using the old semantics.
<akpm@zip.com.au>
[PATCH] pagemap_lru_lock wrapup
Some fallout from the pagemap_lru_lock changes:
- lru_cache_del() is no longer used. Kill it.
- page_cache_release() almost never actually frees pages. So inline
page_cache_release() and move its rarely-called slow path into (the
misnamed) mm/swap.c
- update the locking comment in filemap.c. pagemap_lru_lock used to
be one of the outermost locks in the VM locking hierarchy. Now, we
never take any other locks while holding pagemap_lru_lock. So it
doesn't have any relationship with anything.
- put_page() now removes pages from the LRU on the final put. The
lock is interrupt safe.
<akpm@zip.com.au>
[PATCH] deferred and batched addition of pages to the LRU
The remaining source of page-at-a-time activity against
pagemap_lru_lock is the anonymous pagefault path, which cannot be
changed to operate against multiple pages at a time.
But what we can do is to batch up just its adding of pages to the LRU,
via buffering and deferral.
This patch is based on work from Bill Irwin.
The patch changes lru_cache_add to put the pages into a per-CPU
pagevec. They are added to the LRU 16-at-a-time.
And in the page reclaim code, purge the local CPU's buffer before
starting. This is mainly to decrease the chances of pages staying off
the LRU for very long periods: if the machine is under memory pressure,
CPUs will spill their pages onto the LRU promptly.
A consequence of this change is that we can have up to 15*num_cpus
pages which are not on the LRU. Which could have a slight effect on VM
accuracy, but I find that doubtful. If the system is under memory
pressure the pages will be added to the LRU promptly, and these pages
are the most-recently-touched ones - the VM isn't very interested in
them anyway.
This optimisation could be made SMP-specific, but I felt it best to
turn it on for UP as well for consistency and better testing coverage.

[PATCH] thread management - take three
you have applied my independent-pointer patch already, but i think your
CLEARTID variant is the most elegant solution: it reuses a clone argument,
thus reduces the number of arguments and it's also a nice conceptual pair
to the existing SETTID call. And the TID field can be used as a 'usage'
field as well, because the TID (PID) can never be 0, reducing the number
of fields in the TCB. And we can change the userspace locking code to use
the TID field no problem.

[PATCH] memory leak in current BK
Well I didn't test that very well. __page_cache_release() is doing a
__free_page() on a zero-ref page, so __free_pages() sends the refcount
negative and doesn't free it. With patch #8, page_cache_release()
almost never frees pages, but it must have been leaking a little bit.
Lucky it showed up.
This fixes it, and also adds a missing PageReserved test in put_page().
Which makes put_page() identical to page_cache_release(), but there are
header file woes. I'll fix that up later.

[PATCH] O(1) sys_exit(), threading, scalable-exit-2.5.31-B4

- splits up the global ptrace list into per-task ptrace lists. This was

[PATCH] fix uniprocessor lockups
I have a test_and_set_bit(PG_chainlock, page->flags) in page reclaim.

refill_inactive() cannot move any pages onto the inactive list and the
machine dies.
The patch removes the test_and_set_bit optimisation in there and just
uses pte_chain_lock(). If we want that (dubious) optimisation back

[PATCH] PATCH: fix devices which don't support START_STOP
Based on my discussions with Pete Zaitcev <zaitcev@redhat.com>, I'm
convinced that globally re-writing the START_STOP command into a
TEST_UNIT_READY command is a good idea. This is supported by the fact
that:
(1) Lots of devices don't support START_STOP
(2) Those that do support it often don't do a good job
(3) Win/Mac will never send these commands over a USB bus
So, here's a patch that re-writes them into Test Unit Ready commands. It
seems to work on my system, but needs more testing. There may be a problem
with this code still.... it seems that the SCSI layer can get convinced
that the unit is not ready permanently. I'm honestly not certain what bit
of code is wrong where, so reports from others would be greatly
appreciated.

[PATCH] PATCH: Support for Buffalo 40GB USB hard disk
About 3 weeks ago I sent the following information to the person listed as
the usb-storage maintainer (mdharm-usb@one-eyed-alien.net). I have not
heard back from this person, and for completeness I thought I'd send you
the information at this time as maintainer of the USB stack in general.
In short, the message describes the additional entry in unusual_devs.h which
is needed to get a 40GB Buffalo USB hard disk working under Linux. The
drive has been functioning in the PC now for over 3 weeks with no obvious
sign of problems.
The patch deals with revision "0113" which corresponds to the revision
reported by the drive I have access to. I've included a short comment above
above the unusual_devs definition explaining why the entry is needed. Feel
free to omit this if you feel it's unnecessary bloat.

[PATCH] trivial: 2.5.31+bk forgotten endmenu
<neilb@cse.unsw.edu.au>
[PATCH] Fix two problems with multiple concurrent nfs/tcp connects.
1/ connect requests would be get lost...
As the comment at the top of svcsock.c says when discussing
SK_CONN:
* after a set, svc_sock_enqueue must be called.
We didn't and so lost conneciton requests.
2/ set the max accept backlog to a more reasonable number to cope
with bursts of lots of connection requests.
<neilb@cse.unsw.edu.au>
[PATCH] call svc_sock_setbufsize when socket created.
bufsiz is re-evaluated on recv if SK_CHNGBUF is set,
but recv will never be reached if the buffers are too small.
So we have to set to to something vaguely reasonable
at init time.

<neilb@cse.unsw.edu.au>
[PATCH] md: Silence a warning in md.c
->major_name is "const char *" so we need to sprintf into the kmalloced
space *before* assigning that space to ->major_name.
<neilb@cse.unsw.edu.au>
[PATCH] md: Store rdev instead of bdev in per-personality status arrays
Holding the rdev instead of the bdev does cause an extra
de-reference, but it is conceptually cleaner and will allow
lots more tidying up.
<neilb@cse.unsw.edu.au>
[PATCH] md: MD error handers and md_sync_acct now get rdev instead of bdev
This simplifies the error handlers slighty, but allows for even more
simplification later.
<neilb@cse.unsw.edu.au>
[PATCH] md: Keep track of number of pending requests on each component device on an MD array
This will allow us to know, in the event of a device failure, when the
device is completely unused and so can be disconnected from the
array. Currently this isn't a problem as drives aren't normally disconnect
until after a repacement has been rebuilt, which is a LONG TIME, but that
will change shortly...
We always increment the count under a spinlock after checking that
it hasn't been disconnected already (rdev!= NULL).
We disconnect under the same spinlock after checking that the
count is zero.
<neilb@cse.unsw.edu.au>
[PATCH] md: Remove used_slot field from per-personality info
This is equivalent to ->rdev != NULL, so it isn't needed.
<neilb@cse.unsw.edu.au>
[PATCH] md: Make spare handling simple ... personalities know less
1/ Personalities only know about raid_disks devices.
Some might be not in_sync and so cannot be read from,
but must be written to.
- change MD_SB_DISKS to ->raid_disks
- add tests for .write_only
2/ rdev->raid_disk is now -1 for spares. desc_nr is maintained
by analyse_sbs and sync_sbs.
3/ spare_inactive method is subsumed into hot_remove_disk
spare_writable is subsumed into hot_add_disk.
hot_add_disk decides which slot a new device will hold.
4/ spare_active now finds all non-in_sync devices and marks them
in_sync.
5/ faulty devices are removed by the md recovery thread as soon
as they are idle. Any spares that are available are then added.
<neilb@cse.unsw.edu.au>
[PATCH] md: Improve code for deciding whether to skip an IO in raid5
Instread of the 'skip' variable, just test if rdev is NULL or not.
<neilb@cse.unsw.edu.au>
[PATCH] md: Remove 'alias_device' flag.
This flag was used by multipath to make sure only
one superblock was written, as there is only one
real device.
The relevant test is now more explicitly dependant on multipath,
and the flag is gone.
<neilb@cse.unsw.edu.au>
[PATCH] md: Remove per-personality 'operational' and 'write_only' flags
raid1, raid5 and multipath maintain their own
'operational' flag. This is equivalent to
!rdev->faulty
and so isn't needed.
Similarly raid1 and raid1 maintain a "write_only" flag
that is equivalnt to
!rdev->in_sync
so it isn't needed either.
As part of implementing this change, we introduce some extra
flag bit in raid5 that are meaningful only inside 'handle_stripe'.
Some of these replace the "action" array which recorded what
actions were required (and would be performed after the stripe
spinlock was released). This has the advantage of reducing our
dependance on MD_SB_DISKS which personalities shouldn't need
to know about.
<neilb@cse.unsw.edu.au>
[PATCH] md: Make the old-ioctl warning in md only complain about MD ioctls.
..as some standard ioctls expect the per-device ioctl routine
to return EINVAL and then fall back on a standard implementation.
<neilb@cse.unsw.edu.au>
[PATCH] md: Get rid of un-necessary warning in md
<neilb@cse.unsw.edu.au>
[PATCH] md: Fix up oops-able error message

[PATCH] kNFSd: new error codes for NFSv4
This patch adds new NFSv4-only error codes to include/linux/nfs.h,
and also indicates which of the old error codes still exist in NFSv4.
<kmsmith@umich.edu>
[PATCH] kNFSd: NFSv4: error codes in include/linux/nfsd/nfsd.h
Add some new NFSv4-only error codes to include/linux/nfsd/nfsd.h
<kmsmith@umich.edu>
[PATCH] kNFSd: NFSv4: fix type checking in fh_verify()
Change the type checking in fh_verify(). This fixes a bug which
I reported on the mailing list a few days ago, and also adds a
new error code nfserr_symlink (v4 only). This is returned whenever
an operation which is illegal for symlinks is attempted on a symlink,
and takes precedence over ERR_NOTDIR or ERR_INVAL.
<kmsmith@umich.edu>
[PATCH] kNFSd: NFSv4: change ->rq_vers==3 to ->rq_vers>2
In a few places on the server, I had to change code that looked like:
if (rqstp->rq_vers == 3)
/* NFSv3 behavior */
else
/* NFSv2 behavior */
to:
if (rqstp->rq_vers > 2)
/* NFSv3 behavior */
else
/* NFSv2 behavior */
so that we would get the NFSv3 behavior, not the NFSv2 behavior,
in NFSv4. This patch collects all changes of this type.
<kmsmith@umich.edu>
[PATCH] kNFSd: NFSv4: return err_nofilehandle if missing fh in fh_verify()
Return nfserr_nofilehandle (v4 only) in fh_verify() if the filehandle
has not been set.
<kmsmith@umich.edu>
[PATCH] kNFSd: NFSv4: wipe out all evidence in fh_put()
When a filehandle is cleared with fh_put(), wipe out all traces by
clearing ->fh_pre_saved and ->fh_post_saved. This prevents
fill_post_wcc() from complaining if the filehandle is later reused.
(This could happen in NFSv4 to CURRENT_FH if, for example, LOOKUP LOOKUP
occurs in a COMPOUND.)
<kmsmith@umich.edu>
[PATCH] kNFSd: NFSv4: allow resfh==fhp in fh_compose()
Change fh_compose() so that it will do the right thing if fhp==res_fh.
(This is convenient in the NFSv4 LOOKUP operation, which _replaces_
CURRENT_FH with the filehandle obtained by lookup.)
This requires extracting the interesting parts of the reference
filehandle first, then calling fh_put if it is a re-use.
<kmsmith@umich.edu>
[PATCH] kNFSd: NFSv4: overflow check in nfsd_commit()
Sanity check COMMIT arguments by ensuring that (start)+(length) < 2^64.
The check is done in a way which is free of signedness pathologies in
all cases.
This change was inspired by pynfs, Peter Astrand's regression testsuite
for NFSv4 servers. The change is necessary for all of the COMMIT tests
to pass. However, it's a little open to debate whether the change is
really needed. I'm curious to hear the opinions of other developers.
<kmsmith@umich.edu>
[PATCH] kNFSd: NFSv4: allow type==0 in nfsd_unlink()
If nfsd_unlink() is called with @type equal to 0, then let it do the
right thing regardless of the type of the file being unlinked. This
is needed for the NFSv4 REMOVE operation, which works for any type of
file, even directories.
<kmsmith@umich.edu>
[PATCH] kNFSd: NFSv4: tweak nfsd_create_v3() for NFSv4
File creation in NFSv4 is almost the same as in NFSv3, with one minor
difference. If an UNCHECKED create is done, and the file exists, we
don't set any attributes. Exception: If size==0 is specified as part
of the attributes, then we do truncate the file, but only after processing
the rest of the OPEN. (File creation is always part of an OPEN request.)
This patch defines a new argument *truncp to nfsd_create_v3(), which
will be NULL for v3 requests. For v4 requests, it will point to a
variable which should be set to 1 if file truncation is still needed.
The logic in nfsd_create_v3() is changed as follows: If
- *truncp is not NULL
- the create is UNCHECKED
- the file exists
then nfsd_create_v3() returns immediately. If size==0 is specified,
then *truncp is set to 1.
This is kind of a hack, but the only alternative I could see was creating
a new routine nfsd_create_v4(), which would be identical to nfsd_create_v3()
except for this point.
<kmsmith@umich.edu>
[PATCH] kNFSd: NFSv4: new argument to nfsd_access()
NFSv4 defines a new field in the ACCESS response: a bitmap to indicate
which access bits requested by the client are "supported", i.e. meaningful
for the object in question.
This patch adds a new parameter @supported to nfsd_access(), so that
nfsd_access() can set the value of this bitmap.
<kmsmith@umich.edu>
[PATCH] kNFSd: NFSv4: tweak nfsd_readdir() for NFSv4
This patch makes three small changes to nfsd_readdir().
First, the 'filldir' routine for NFSv4 may return an arbitrary error,
which should become the return value for nfsd_readdir(). I implemented
this by adding an 'nfserr' field to the 'struct readdir_cd'.
Second, in NFSv4 the caller of nfsd_readdir() will specify an attribute
bitmap, which must be communicated to the 'filldir' routine. I implemented
this by adding a @bitmap parameter to nfsd_readdir() and a corresponding
field in the 'struct readdir_cd'. (The bitmap is not interpreted in any
way by nfsd_readdir().)
Finally, NFSv4 defines a new error nfserr_readdir_nospc, which indicates
that there was not enough buffer space to encode a single entry.

kbuild: remove duplicated dependencies
Greg Banks:
A number of dep_bools and dep_tristates have architecture constants
(e.g. CONFIG_X86) as dependencies. Such symbols have the property
that their value is constant for any particular arch tree, and is
either "y" or "", neither of which have any effect as dependencies,
so the dependencies have no effect. This patch removes some of them.

Introduce struct device_class
Device classes describe a type (or class) of device, like an input device
or network device, etc. This changeset defines a struct device_class that
each subsystem is expected to implement and register with the core.
struct device_driver gains a devclass pointer which points to the class it
belongs to. When the driver is registered, it is added to the class's list
of drivers. Whenever a device is bound to that driver, it is added to the
class by calling the class's add_device callback.
struct device gains a class_num field which is the per-class enumerated value
of the device. It is incremented each time a device is registered with the
class.
Each device class gets a driverfs directory in class/<class name> and two
subdirectories: 'devices' and 'drivers'. For each device added to the class,
a symlink is created in the devices/ directory that points to the device's
directory in the physical hierarchy. The name of the symlink is the enumerated
number the device got when it was registered with the class.
For each driver that's added to the class, a symlink is created in the class's
drivers/ directory that points to the driver's directory. The name of this
symlink is a concatenation of <bus name>:<driver name> (to prevent namespace
conflicts of drivers with the same name on different buses).
<mochel@osdl.org>
Introduce struct device_interface.
Device interfaces are the logical interfaces of device classes that correlate
directly to userspace interfaces, like device nodes.
Device interfaces are registered with the class they belong to. As devices
are added to the class, they are added to each interface registered with
the class. The interface is responsible for determining whether the device
supports the interface or not.
The interface is responsible for allocating and initializing a struct
intf_data and calling interface_add_data() to add it to the device's list
of interfaces it belongs to. This list will be iterated over when the device
is removed from the class (instead of all possible interfaces for a class).
This structure should probably be embedded in whatever per-device data
structure the interface is allocating anyway.
Devices are enumerated within the interface. This happens in interface_add_data()
and the enumerated value is stored in the struct intf_data for that device.
Interfaces get a directory in driverfs under their class's directory. Each
time a device is added to the interface, a symlink is created in that
directory that points to the device's directory in the physical hierarchy.
The name of this symlink is the interface-enumerated value of the device.
