2.5.43 long-format changelog
Summary of changes from v2.5.42 to v2.5.43
============================================
<acme@conectiva.com.br>
o pppoe: use seq_file for proc stuff
Also make it conditional on CONFIG_PROC_FS
<shaggy@kleikamp.austin.ibm.com>
JFS: change name of get_index() to read_index()
get_index conflicts with a symbol in a mips include file.
<sarolaht@cs.helsinki.fi>
[TCP]: Add F-RTO support.
Motivation for this modification is that especially on some wireless
network technologies there are delay spikes that trigger RTO even though
no packets are lost. F-RTO sender continues by sending new data after RTO
retransmission in order to avoid unnecessary retransmissions in that case.
If the sender sees any duplicate acks after the RTO retransmission, it
reverts to traditional slow start retransmissions. If new acks arrive
after forward transmissions, they very likely indicate that the RTO was
indeed spurious and the sender can continue sending new data (because
only one segment was retransmitted).
<davem@nuts.ninka.net>
arch/sparc64/defconfig: Update.
<davem@nuts.ninka.net>
[TCP]: Only non-zero inits are necessary in tcp_vX_init_sock.
<sarolaht@cs.helsinki.fi>
[TCP]: Turn F-RTO off by default.
<bcrl@bob.home.kvack.org>
net-kiocb.diff
<bcrl@bob.home.kvack.org>
clean up whitespace and patch import errors from net-kiocb patch
<bcrl@redhat.com>
eliminate a compiler warning for aio_write in net/socket.c
<bcrl@redhat.com>
correct sock_aio_write prototype
<bcrl@bob.home.kvack.org>
remove an inaccurate comment from sock.h
<davem@nuts.ninka.net>
arch/sparc64/kernel/ebus.c: Cure __FUNCTION__ usage.
<stuartm@connecttech.com>
[PATCH] USB Whiteheat driver patches
A couple patches on 2.5.41; issues discovered during QA.
1: The hack to get around the unlinking bug. You said this was also in
2.5.x, so I've included this.
2: filp is NULL when called from usb_serial_disconnect. Fixes an oops.
3: In the case where the module is reloaded; the endpoints in the
usbsubsystem don't go away. So when the module comes back, the
endpoints still have the unlink thing, and also need to be cleared.
Otherwise the firmware appears not respond to the version nubmer query
and the driver doesn't attach, and you have no device.
<randy.dunlap@verizon.net>
[PATCH] "nousb" for in-kernel USB
Here's the updated "nousb" patch for vanilla 2.5.41.
It applies with 2 small offsets to 2.5.41-bk3.
<ddstreet@ieee.org>
[PATCH] fix usbfs mount count
Hi, this patch fixes usbfs. You can't use a single mount_count for 2
different mounts.
<wli@holomorphy.com>
[PATCH] remove unused variable in wacom driver
wacom.c generates the following warning:
drivers/usb/input/wacom.c: In function `wacom_probe':
drivers/usb/input/wacom.c:405: warning: unused variable `rep_data'
<zaitcev@redhat.com>
[SPARC]: Fix build of timer routines.
<adam@yggdrasil.com>
[PATCH] linux-2.5.41/drivers/usb/core/hub.c called down() from interrupt context
On second thought after reading Oliver Neukum's question about
"shaving off a cycle or two", here is version of my fix for down()
being called from interrupt context that uses unlikely() to get the
speed advantage that would be available from BUG_ON(), while still
ensuring that the condition is executed even if assertions are
compiled out.
<davem@nuts.ninka.net>
[IPV4]: Use generic struct flowi as routing key.
<davem@nuts.ninka.net>
net/ipv6/netfilter/ip6table_mangle.c: Fix wrong cast.
<acme@conectiva.com.br>
[ipv4] move proc init to newly created net/ipv4/ip_proc.c
This is the start of the seq_file work, so that I can see if anybody
will cough too much on the choosen path...
Also convert some unneeded __constat_htons to plain htons, that results
in the same code being generated.
<davem@nuts.ninka.net>
net/ipv4/af_inet.c: Include linux/igmp.h
<davem@nuts.ninka.net>

<stevef@smfhome1.austin.rr.com>
change name of debug function to not conflict with optional jfs debug function
<davem@nuts.ninka.net>
fs/aio.c: Export wait_on_sync_kiocb.
<dilinger@mp3revolution.net>
drivers/scsi/esp.c: Fix the build.
<bgerst@didntduck.org>
[PATCH] convert tty_drivers to list_heads
Convert the tty_drivers list to use list_heads instead of open coded
doubly-linked lists.
<bunk@fs.tum.de>
[PATCH] Fix cpufreq compile
The timer-handling split patch moved cpufreq stuff from time.c to
timers/timer_tsc.c but not the corresponding #include <linux/cpufreq.h>
causing the build to fail.
The fix is simple.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Fix UML build
Not perfectly clean yet, but uses the standard way to descend into subdirs
and gives me working vmlinux and linux targets without spurious rebuilds.
<rread@clusterfs.com>
[PATCH] InterMezzo for 2.5
This is the initial port of InterMezzo for 2.5. It now compiles,
mounts, and completes I/Os successfully, but we are aware that more
needs to be done and we will do it as quickly as possible.
<torvalds@home.transmeta.com>
Merge with DRI CVS tree
<bunk@fs.tum.de>
[PATCH] ATM build fix
Fix buggy #if removal in iphase.c that crept in with the initcalls fixup.
<torvalds@home.transmeta.com>
When opening a CD-ROM device with O_NONBLOCK (for setup and ioctl),
we should allow read-write accesses - it's used for control, not
data.
<manfred@colorfullife.com>
[PATCH] oneliner race fix for ldt updates
Problem: if another CPU is using lazy-TLB, the LDT flushing won't flush
the other CPU's LDT entry.
Fix: use active_mm instead of mm for the flush IPI.
<rth@splat.sfbay.redhat.com>
Fix warnings of the form
warning: long int format, different type arg (arg 5)
by casting ino_t arguments to unsigned long for printf formats.
In some instances, change %ld to %lu.
<rth@splat.sfbay.redhat.com>
Fix warnings of the form
warning: right shift count >= width of type
by casting to long before shifting by HIGH_BITS_OFFSET.
<rth@splat.sfbay.redhat.com>
Fix illegal use of short keyword.
<rth@splat.sfbay.redhat.com>
Fix three alpha gcc 3.3 warnings.
<rth@splat.sfbay.redhat.com>
Fix two defined but not used warnings by wrapping the
variables in #if RTC_IRQ.
<rth@splat.sfbay.redhat.com>
Fix hordes of printf format warnings by changing loff_t to long long.
<rth@splat.sfbay.redhat.com>
Fix defined but not used warnings by marking variables
with attribute unused.
<rth@are.twiddle.net>
From Art Haas: C99 initializers for arch/alpha.
<rmk@flint.arm.linux.org.uk>
[SERIAL] Fix Sparc32/64 handling of CONFIG_SERIAL_CORE{,_CONSOLE}
SPARC was unconditionally setting CONFIG_SERIAL_CORE_CONSOLE to y
and conditionally setting CONFIG_SERIAL_CORE depending on the Sparc
sub-drivers. In addition, the core serial driver for SPARC is
always built, so we end up with link errors.
We instead make CONFIG_SERIAL_CORE{,_CONSOLE} dependent on building
the SPARC core driver (CONFIG_SERIAL_SUNCORE).
<ak@muc.de>
[PATCH] x86-64 ACPI
ACPI updates for x86-64/2.5.42
ACPI finally works now.
<ak@muc.de>
[PATCH] x86-64 Bootloader updates
Update the early 32bit bootloader for x86-64. This stuff is near
completely identical to i386, except for a few Makefile changes to tell
the x86-64 toolkit to compile in 32bit mode.
<ak@muc.de>
[PATCH] x86-64 - new memory map handling
New e820 memory map handling for x86-64. Move it all to a new file and
clean it up a lot. Add some simple allocator functions to deal with
holey e820 mappings cleanly A lot of this is preparation for NUMA (which
works in 2.4, but is not ported to 2.5 yet)
<ak@muc.de>
[PATCH] x86-64 IA32 emulation updates
Some bugfixes for the 32bit emulation for x86-64 and make it all compile
again.
Has rewritten ioctl registration code and some other updates. New
system calls are supported.
It unfortunately broke some time ago by binfmt_elf changes for all
shared linked libraries. Will fix that later.
<ak@muc.de>
[PATCH] x86-64 IOMMU & PCI updates
Update for the x86-64 PCI subsystem in 2.5.42. Main new feature is PCI
IOMMU support through the K8 aperture. This allows to use more than 4GB
of memory with 32bit PCI devices. Also some other PCI changes, mostly
merges from i386.
<ak@muc.de>
[PATCH] Remove global cli stuff for x86-64
Straightforward merge from i386: remove support for global cli for
x86-64
<ak@muc.de>
[PATCH] reboot.c for x86-64
Merge from i386 for x86-64: move reboot functions to an own file.
<ak@muc.de>
[PATCH] library functions updates for x86-64
Update various lib/ functions for x86-64:
- new memcpy/memset/csum-copy/copy_page/user
- add bitstr support function for IOMMU
- Other minor fixes and updates.
<ak@muc.de>
[PATCH] hotplug cpu changes for x86-64
Port of the hotplug CPU changes from i386 for x86-64. I don't expect
x86-64 hardware to support CPU hotplugging any time soon, but this makes
it all compile & work again and keeps some consistency.
<ak@muc.de>
[PATCH] Time changes for x86-64
Some timer updates from Vojtech Pavlik for x86-64. In theory support
HPET timing now, but the support is disabled.
Would actually need vxtime_lock() macros in the generic timer code to
protect xtime updates, but I'm leaving that out now because it's only
needed for vsyscalls and they're currently disabled.
<ak@muc.de>
[PATCH] Misc core changes for x86-64/2.5.42
And here all the other x86-64 changes that have accumulated in my tree.
It's various bugfixes and cleanups.
Changes:
- fix nmi watchdog
- remove local timer spreading over CPUs - it's useless here and caused many problems
- New offset.h computation from Kai
- Lots of changes for the C99 initializer syntax
- New MTRR driver from Dave & Mats
- Bugfix: kernel threads don't start with interrupts disabled anymore, which fixes
various boottime hangs (this was fixed a long time ago, but the bug crept in again
by the backdoor)
- Do %gs reload in context switch lockless
- Fix device_not_available entry point race
- New per CPU GDT layout following i386: the layot is not completely
compatible with i386, which may problems with Wine in theory.
Haven't seen any yet.
- Support disableapic option
- driverfs support removed for now because it caused crashes
- Updates for new signal setup
- Support for kallsyms
- Port TLS clone flags/syscalls: unfortunately made the context switch
even uglier than it already is.
- Security fixes for ptrace
- New in_interrupt()/atomic setup ported from i386
- New makefiles mostly from Kai
- Various updates ported from i386
<torvalds@home.transmeta.com>
Fix type - it used to be "__u8 short", which previous versions
of gcc incorrectly accepted as "short". It got fixed to __u8, but
it really should be __u16.

[PATCH] forward port of the various scsi fixes from 2.4
<bcollins@debian.org>
[PATCH] Linux IEEE-1394 Updates
- Cleanup (purge) some of our old compat code (never thouched)
- Fix dv1394 compilation warnings without devfs
- Added new config-rom handling features. Allows for on-the-fly
config-rom generation for dynamic functionality of the host nodes.
- Convert to workqueue from taskqueue interfaces. This is actually
abstracted compatibility code between tqueue/workqueue.
<hirofumi@mail.parknet.co.jp>
[PATCH] fix error code which fat_fill_super() returns (1/5)
This fixes the error code which fat_fill_super() returns.
<hirofumi@mail.parknet.co.jp>
[PATCH] merges parse_options() of fat and parse_options() of vfat (2/5)
This merges parse_options() of fat and parse_options() of vfat.
And this doesn't recognize the unknown options.
<hirofumi@mail.parknet.co.jp>
[PATCH] removes posix option of fat (3/5)
This removes the posix option of vfat. The current posix options works
only as an alias of name_check=s.
<hirofumi@mail.parknet.co.jp>
[PATCH] add show_options to fat (4/5)
This adds fat_show_options() to fat. And instead, this doesn't output
the charset name in fat_fill_super().
<hirofumi@mail.parknet.co.jp>
[PATCH] adds dmask option to fat (5/5)
This adds the dmask option. Yes, the dmask option is the permission
bitmask for directory.
<bcollins@debian.org>
[PATCH] Dv1394 fix
This patch fixes a typo introduced by my last patch to dv1394.
<maxk@qualcomm.com>
Fix typo in HCI_FILTER get/setsockopt
<acme@conectiva.com.br>
o ipv4: convert /proc/net/arp to seq_file
<rmk@flint.arm.linux.org.uk>
[ARM] Move TEXTADDR and DATAADDR out of vmlinux.lds.S
These two variables are used by more than just the linker;
they're also used by head.S to know where it can safely
place the page tables. We therefore need to export it
from the Makefile.
These are also highly machine dependent; we don't want
to duplicate the same set of conditionals for cpp and
for the makefiles.
arch/arm/Makefile also contained a stray close-paren. I'm
submitting this one to the lost property office.
We also always pass -mno-fpu to the assember; this
guarantees that any floating point will be caught.
<rmk@flint.arm.linux.org.uk>
[ARM] Allow CONFIG_ZBOOT_ROM=y image to be relocated to RAM
Since the decompressor supports PIC, even for CONFIG_ZBOOT_ROM,
we can easily allow an image which has been linked to run at
a particular address in ROM to be moved to RAM. We just need
to make sure that we don't relocate the GOT entries for the
BSS segment.
This cset also implements sa1100-based debugging for the
decompressor.
<rmk@flint.arm.linux.org.uk>
[ARM] Ensure deselected config variables are defined to 'n'
To keep the Config.in files relatively clean, we use the
following construct:
if [ "$CONFIG_ARM" = "y" ]; then
dep_tristate 'Foo' CONFIG_FOO $CONFIG_BAR
fi
where CONFIG_BAR is some machine implementation or high-level
chip support configuration option. If CONFIG_BAR is left
empty, then the tristate is offered to the user, which isn't
what we want. Defining CONFIG_BAR to 'n' prevents the option
being offered.
This is a rule I generally try to implement within
arch/arm/config.in.
This cset makes CONFIG_SA1111 and CONFIG_ARM_THUMB behave that
way.
<rmk@flint.arm.linux.org.uk>
[ARM] Update timekeeping functions to use tick_nsec/1000
This updates the ARM time keeping functions to use tick_nsec/1000
instead of tick.
<rmk@flint.arm.linux.org.uk>
[ARM] Update pcibios_enable_device, supply pci_mmap_page_range()
Update pcibios_enable_device to only enable requested resources,
mainly for IDE. Supply a pci_mmap_page_range() function to allow
user space to mmap PCI regions.
<rmk@flint.arm.linux.org.uk>
[ARM] Update for signal handling changes.
<rmk@flint.arm.linux.org.uk>
[ARM] Update RiscPC decompressor for PIC changes
This cset fixes the RiscPC decompressor code for the PIC changes.
We use a pointer to a structure rather than a structure to access
params. With a PIC decompressor, the address of the structure gets
PIC-ified which is not what we want.
<rmk@flint.arm.linux.org.uk>
[ARM] Optimise ARM TLB handling
Sanitise includes of asm/tlbflush.h, asm/cacheflush.h, asm/proc-fns.h
Implement ARM-specific TLB "shootdown" code. It turns out that it
is overall more efficient to unconditionally invalidate the whole
TLB rather than entry by entry when removing areas.
<rmk@flint.arm.linux.org.uk>
[ARM] Update neponset/sa1111 for Linux device model updates.
This updates these neponset and sa1111 support to use the new system
device infrastructure in the Linux device model.
<rmk@flint.arm.linux.org.uk>
[ARM] Other updates for changes in 2.5.42
This adds ARM support for in_atomic() and asm/numnodes.h
<rmk@flint.arm.linux.org.uk>
[ARM] IDE updates
- ide_register_hw takes two arguments, not one.
- ide_fix_driveid is no longer used.
<rmk@flint.arm.linux.org.uk>
[ARM] Fix iop310-pci compilation errors.
<rmk@flint.arm.linux.org.uk>
[ARM] Remove second serial port address.
The second serial port is never present in these machines, so its
pointless listing it in the first place.
<rmk@flint.arm.linux.org.uk>
[ARM] cpufreq updates for ARM
This updates the Integrator cpufreq code to use the new interfaces,
and makes the sa1100 cpufreq round up the requested frequency.
<rmk@flint.arm.linux.org.uk>
Convert acorn expansion card probing code to the Linux device model.
Provide LDM-based driver registration/removal interface for drivers
to use. We make the old device discovery code ignore devices
claimed via the LDM framework. However, the LDM framework ignores
devices that may be in use by the old device discovery code. This
is fine since the only devices that will still use the old discovery
code will be SCSI drivers.
Currently, we don't provide a useful dev.name entry.
<rmk@flint.arm.linux.org.uk>
[ARM] Update Acorn ethernet expansion cards
This cset implements validity checks on the ethernet MAC address when
the device is opened, and refuses to open the device if this check
fails. We also provide the set_mac_address method to allow ifconfig
to change the mac address to something valid.
In addition, the driver is converted from the old expansion card
discovery methods to the new device model driver framework.
<rmk@flint.arm.linux.org.uk>
[ARM] Acorn serial port driver update
This cset combines the Atomwide and The Serial Port 16550 driver
modules into one "8250_acorn.c" driver. This new module takes full
advantage of the LDM-based expansion card facilities.
<rmk@flint.arm.linux.org.uk>
[ARM] Remove old Acorn iomd-based keyboard and mouse drivers.
Vojtech has patches that bring their counterparts in the input
subsystem up to date (and into a working state) so these drivers
are no longer required.
This cset also fixes the Acorn i2c RTC code.
<rmk@flint.arm.linux.org.uk>
[ARM] Fix up NCR5380-based Acorn SCSI drivers
This cset updates (as much as is possible) the NCR5380-based Acorn
SCSI drivers, mainly converting them to the new error handling code.
However, they still don't build due to errors in NCR5380.
<rmk@flint.arm.linux.org.uk>
[ARM] Rudimentary support for Thumb ptracing.
Add rudimentary support for Thumb ptracing; we aren't able to single
step through thumb branches yet, but this change provides enough
infrastructure to make this possible.
<rmk@flint.arm.linux.org.uk>
[ARM] dump_stack and show_trace_task
dump_stack() got used by the generic code. Call our version
__dump_stack since we're running out of other descriptive names.
Allow show_trace_task to show the backtrace for the current
thread.
<rmk@flint.arm.linux.org.uk>
[ARM] Remove non-existent USB gadget code from mach-sa1100/Makefile
The USB gadget code now lives in arch/arm/mach-sa1100/usb, and
isn't in a mergable state. We remove the old makefile entries
which are never going to be satisfied, and leave a placeholder for
the usb directory.
<perex@suse.cz>
ALSA update
- reduced stack usage (>1024 bytes) in ioctl32 routines and PCM routines
- PCM midlevel - fixed drop in release()
- OPL3SA2 - removed wrong inclusion of <linux/isapnp.h>
- EMU8000 - fixed compilation when sequencer is not selected
- Wavefront - fixed compilation for GCC3
- fixed gameport dependency in pci/Config.in
- EMU10K1 - fixed icode peek ioctl in emufx()
- YMFPCI - added FM legacy volume control
<rmk@flint.arm.linux.org.uk>
[ARM] Convert boot-time memory permission selection to table.
This removes a compilation warning and makes the code smaller.
It is also more obvious what's going on.
<rmk@flint.arm.linux.org.uk>
[ARM] Update fd1772.c
Remove unnecessary use of __inline__, and remove a few unnecessary
prototypes. copy_buffer is moved before use.
<rmk@flint.arm.linux.org.uk>
[ARM] Fix fas216 use of __FUNCTION__ macro.
<perex@suse.cz>
ALSA update
- fixes for compilation without CONFIG_PROC_FS
<rmk@flint.arm.linux.org.uk>
[ARM] Update acorn scsi code wrt global irq and bitops
This cset removes the global irq handling in the AcornSCSI driver,
and makes the target type for bitops an unsigned long array rather
than an unsigned char array.
<rmk@flint.arm.linux.org.uk>
[ARM] Fix entry-armv.S
Prevent the assembler putting constant pools in the middle of code.
Clean up shark ISA PIC handling.
<perex@suse.cz>
ALSA update
- added SNDRV_PCM_IOCTL_HWSYNC ioctl
- changed behaviour of read/write/poll functions
- prefer waiting than return an error code
- removed snd_seq_sleep_timeout_in_lock and snd_seq_sleep_in_lock helpers
<rmk@flint.arm.linux.org.uk>
[ARM] Update ARM cache type decoding.
<rmk@flint.arm.linux.org.uk>
[ARM ADFS] C99 designated initialisers (Patch from Art Haas)
Here's a small set of patches that switch the code to use C99
desiginated initializers. Patches are against 2.5.42.
<rmk@flint.arm.linux.org.uk>
[ARM] Convert sa1100 PCMCIA drivers to C99 initializers (Art Haas)
The patches convert drivers/pcmcia to use C99 named initializers,
and all the patches are against 2.5.42. There are 25 patches in
total, and the "cat"ing them together they're more that 20K, so
I'm sending the patches as a compressed attachment. The patches
were CC'd to Linus in the first mail that bounced.
<rmk@flint.arm.linux.org.uk>
[ARM] Make the assabet machine always use the same uart mapping.
Traditionally, the Assabet reverses its mapping of UART1 and UART3
when the Neponset board is connected. This can be (a) confusing
and (b) annoying when the boot loader uses UART1. We therefore
have a fixed mapping between the ttySA names and the physical
UARTs on this platform.

[PATCH] /proc/meminfo alterations for hugetlbpages
The patch from Rohit and David M-T changes the hugetlb page info in

It makes the identifiers a little clearer while ensuring that we don't
add any identifiers which have whitespace. glibc is/shall be parsing
this information to determine the size and alignment requirements of
the hugetlb pages.
This basically means that procfs is a requirement for successful
hugetlb page usage. Not very nice, but I suspect real-world userspace
fails without procfs anyway.

There was a corner case in the conversion of direct-io to use

and use that in the new BIO if we have to open a new one.

[PATCH] page freeing function for swsusp
Software suspend needs a way of forcing page reclaim, up to the point
where 50% of memory is free.
This patch implements a function to do that:
int shrink_all_memory(int nr_pages);
Will attempt to reclaim `nr_pages' pages and return them to the free
pages pool. It returns the number of pages which it actually freed.
If called with a "large" number of pages it will only free up to a few
hundred, so the caller needs to loop on it.
If it returns zero then there is no point in calling it again.
<akpm@digeo.com>
[PATCH] small-machine writer throttling fix
The current writer throttling in balance_dirty_pages() assumes that the
writer will be effectively throttled on request queues.
That works fine when the amount of data which can be placed into a
queue is "much less than" total memory.
But if the machine has a small amount of memory, or many disks, or has
large request queues, or large requests, it can go wrong.
For example, with mem=96m and dirty_async_ratio=15, we want to be able
to clamp dirty+writeback memory at 15 megabytes. But it doesn't work,
because a single SCSI request queue can hold 40 megs or more. The
heavy writer keeps on dirtying memory until that queue fills up.
So add a test for that - if we did some writeback, and we're *still*
over the dirty+writeback threshold then make the caller take an
explicit nap on some writes terminating. And keep on doing that until
the dirty+writeback memory subsides.

[PATCH] propagate pte reference into page reference during
zap_pte_range() is currently just dropping the pte. Change it to mark
the page referenced if the pte says it was. This has the effect of
delaying the eviction of recently-mapped pagecache.
This means that we're currently marking the page accessed when it is
first faulted in as well as when we drop it from pagetables. Which
matches up with the (strange) behaviour of the VM: it reclaims
PageReferenced pagecache pages off the inactive list.
Probably, it makes sense to remove the mark_page_accessed() from
filemap_nopage() and just use the pte bits everywhere. Reviewing all
the PageReferenced()/mark_page_accessed() usage is on my todo list.
<akpm@digeo.com>
[PATCH] reduced and tunable swappiness
/proc/sys/vm/swappiness controls the VM's tendency to unmap pages and to
swap things out.
100 -> basically current 2.5 behaviour
0 -> not very swappy at all
The mechanism which is used to control swappiness is: to be reluctant
to bring mapped pages onto the inactive list. Prefer to reclaim
pagecache instead.
The control for that mechanism is as follows:
- If there is a large amount of mapped memory in the machine, we
prefer to bring mapped pages onto the inactive list.
- If page reclaim is under distress (more scanning is happening) then
prefer to bring mapped pages onto the inactive list. This is
basically the 2.4 algorithm, really.
- If the /proc/sys/vm/swappiness control is high then prefer to bring
mapped pages onto the inactive list.
The implementation is simple: calculate the above three things as
percentages and add them up. If that's over 100% then start reclaiming
mapped pages.
The `proportion of mapped memory' is downgraded so that we don't swap
just because a lot of memory is mapped into pagetables - we still need
some VM distress before starting to swap that memory out.
For a while I was adding a little bias so that we prefer to unmap
file-backed memory before swapping out anon memory. Because usually
file backed memory can be evicted and reestablished with one I/O, not
two. It was unmapping executable text too easily, so here I just treat
them equally.
<akpm@digeo.com>
[PATCH] start anon pages on the active list
We're currently adding anon pages to the inactive list. But they're
all referenced, so when they reach the tail of the inactive list the
kernel will always then bump them up to the active list.
Not only does this waste CPU, but it leads to inactive/active
imbalance. We end up with enormous sequences of unreclaimable,
to-be-activated pages hitting the tail of the LRU and large amounts of
scanning need to be done. Which upsets the VM, making it think that it
is "under distress".
So just start them out on the active list.
<akpm@digeo.com>
[PATCH] rename /proc/sys/vm/dirty_async_ratio to dirty_ratio
Since /proc/sys/vm/dirty_sync_ratio went away, the name
"dirty_async_ratio" makes no sense.
So rename it to just /proc/sys/vm/dirty_ratio.
<akpm@digeo.com>
[PATCH] reduce the dirty threshold when there's a lot of mapped
Dirty memory thresholds are currently set by /proc/sys/vm/dirty_ratio.
Background writeout levels are controlled by
/proc/sys/vm/dirty_background_ratio.
Problem is that these levels are hard to get right - they are too
static. If there is a lot of mapped memory around then the 40%
clamping level causes too much dirty data. We do lots of scanning in
page reclaim, and the VM generally starts getting into distress. Extra
swapping, extra page unmapping.
It would be much better to simply tell the caller of write(2) to slow
down - to write out their dirty data sooner, to make those written
pages trivially reclaimable. Penalise the offender, not the innocent
page allocators.
This patch changes the writer throttling code so that we clamp down
much harder on writers if there is a lot of mapped memory in the
machine. We only permit memory dirtiers to dirty up to 50% of unmapped
memory before forcing them to clean their own pagecache.

[PATCH] USB: 2.5.42 partial fix for older pl2303

> Now, would you mind taking a look at 2.5, and fixing this there too? :)
Here's a half-successful attempt. With this patch, the device no longer
appears twice, and it always works on the first open (at least, so I've
observed up to this point). The open following a successful open usually
fails (roughly speaking, it appears to play dead), and the open following
a failed open usually (always?) succeeds.
So, on my PL-2303, it's not perfect but it's certainly livable.
This patch is based on the one I did for 2.4, and in fact, this code
functions when it's plugged into 2.4.20-pre10 instead of 2.5.42. In that
scenario, the opens work 100% of the time.
I'd be interested in suggestions or comments regarding this patch.
Anyone who has a PL-2303 working under 2.5 might want to try this patch
just to make sure it doesn't kill their working setup.

[PATCH] usbcore doc + minor fixes
Cleaning out my queue of most minor patches:
- Provides some kerneldoc for 'struct usb_interface' now that
the API is highlighting it.
- Fixes usb_set_interface() so it doesn't affect other interfaces.
This provides the right place for an eventual HCD call to clean
out now-invalid records of endpoint state, and also gets rid of
a potential SMP issue where drivers on different interfaces
calling concurrently could clobber each other. (Per-interface
data doesn't need locking except against config changes.)
- It's OK to pass URB_NO_INTERRUPT hints if you're queueing a
bunch of interrupt transfers.
The set_interface call should eventually take the interface as a
parameter, it's one of the few left using the "device plus magic
number" identifier. I have a partial patch for that, but it doesn't
handle the (newish) ALSA usb audio driver or a few other callers.

[PATCH] batched slab shrink and registration API
From Ed Tomlinson, then mauled by yours truly.
The current shrinking of the dentry, inode and dquot caches seems to
work OK, but it is slightly CPU-inefficient: we call the shrinking
functions many times, for tiny numbers of objects.
So here, we just batch that up - shrinking happens at the same rate but
we perform it in larger units of work.
To do this, we need a way of knowing how many objects are currently in
use by individual caches. slab does not actually track this
information, but the existing shrinkable caches do have this on hand.
So rather than adding the counters to slab, we require that the
shrinker callback functions keep their own count - we query that via
the callback.
We add a simple registration API which is exported to modules. A
subsystem may register its own callback function via set_shrinker().
set_shrinker() simply takes a function pointer. The function is called
with
int (*shrinker)(int nr_to_shrink, unsigned int gfp_mask);
The shrinker callback must scan `nr_to_scan' objects and free all
freeable scanned objects. Note: it doesn't have to *free* `nr_to_scan'
objects. It need only scan that many. Which is a fairly pedantic
detail, really.
The shrinker callback must return the number of objects which are in
its cache at the end of the scanning attempt. It will be called with
nr_to_scan == 0 when we're just querying the cache size.
The set_shrinker() registration API is passed a hint as to how many
disk seeks a single cache object is worth. Everything uses "2" at
present.
I saw no need to add the traditional `here is my void *data' to the
registration/callback. Because there is a one-to-one relationship
between caches and their shrinkers.
Various cleanups became possible:
- shrink_icache_memory() is no longer exported to modules.
- shrink_icache_memory() is now static to fs/inode.c
- prune_icache() is now static to fs/inode.c, and made inline (single caller)
- shrink_dcache_memory() is made static to fs/dcache.c
- prune_dcache() is no longer exported to modules
- prune_dcache() is made static to fs/dcache.c
- shrink_dqcache_memory() is made static to fs/dquot.c
- All the quota init code has been moved from fs/dcache.c into fs/dquot.c
- All modifications to inodes_stat.nr_inodes are now inside
inode_lock - the dispose_list one was racy.

[PATCH] fix disk IO stats for 512-byte IOs
If you're peforming 512-byte sized IOs. With, say,

XFS: Rework dev_t and linux inode handling
This is a two fold change, first it moves the translation between
linux dev_t and kdev_t up the call stack in xfs and makes the bulk
of xfs work in terms of its on disk dev_t format. It also cleans
up a few related chunks of code.
The other part of the change reworks how we keep the linux inode
contents and the xfs inode fields in sync. A number of places where
we resynced the two have been removed, these were basically
replicating work elsewhere in the filesystem. We now also ensure
that the inode fields are filled in before calling unlock_new_inode -
there used to be a window.
Finally all the code which hooks together the linux inode and the xfs
inode is brought together as a more coherent whole rather than being
cattered around the inode create path. Most calls to revalidate the
linux inode from the xfs inode are removed.

XFS: Switch to native endian internal representation for extents
Switch xfs from using a big endian internal representation for
the in memory copy of extents to a host byte order representation.
The internal extents are read in once, then modified seperately
from the on disk ones. Since we search and manipulate the extents
multiple times, it is cheaper to convert them to host byte order
once and then keep them in that format. Worth about 5 to 10%
reduction in cpu time for some loads. Complicated by the fact
that the in memory extents are written out to the log sometimes,
and when expanding extents are used to write out the initial
block of extents.

XFS: Fix a couple of nasty log problems
When a transaction crosses multiple iclogs, the async transaction code
needs to force the log up until the last iclog. We need to record this
lsn in the transaction so we can do a log flush on it.
Secondly, there was a sleep/wakeup pair between flushing the log and
log write completions which was a) incorrect, and b) no longer needed.
This could result in early wakeups of threads waiting for log flushes.

[PATCH] early allocation of ->part
allocation of ->part[] moved to alloc_disk(); alloc_disk() got an
argument (number of minors expected). Freeing is in put_disk().
<viro@math.psu.edu>
[PATCH] disk->minor_shift cleanup
new field - disk->minors (1 << disk->minor_shift). Almost all uses
of ->minor_shift had that form and thus had been replaced.
<viro@math.psu.edu>
[PATCH] device_register() splitup
new driverfs helpers - device_initialize/device_add and device_del.
The latter is device_unregister() sans the final put_device(). The former
is splitup of device_register() into initialization and insertion into tree.
<viro@math.psu.edu>
[PATCH] block ioctl cleanup
guts of blkpg.c and blkdev_ioctl() sanitized up and moved into a new
file - drivers/block/ioctl.c. blkpg.c is gone.
<viro@math.psu.edu>
[PATCH] preparation to use of driverfs refcounts, part 1 - partitions
* update_partition() split into add_partition() and delete_partition().
* all updating of ->part[] is switched to these two (including initial
filling/final cleaning).
* per-partition devices are allocated on-demand and never reused.
We allocate struct device in add_partition() and put reference to it into
hd_struct. ->release() for that struct device frees it. delete_partition()
removes reference from hd_struct and does put_device() on it. Basically,
we get rid of problems with reused struct device by never reusing them...
At that point devices for partitions are nice and sane.
<viro@math.psu.edu>
[PATCH] preparation to use of driverfs refcounts, part 2 - disk
* disk->disk_dev is initialized in alloc_disk(), device_add()'d in
add_disk(), device_del()'d in unregister_disk() and device_put() in
put_disk().
* devices of partitions are made its children.
* attributes of disk one: dev (dev_t of the thing), range (number of
minors) and size (in sectors).
* attributes of partition ones: dev (ditto), start (in sectors) and
size (in sectors).
* disk devices are put on a new bus - "block"
* if caller of add_disk() had set disk->driverfs_dev, we set symlinks:
"device" from disk to underlying device and "block" from underlying
device to disk.
* ->release() of disk_dev frees disk and disk->part.
At that point we have sane driverfs subtree for each gendisk and
refcount of its root (disk->disk_dev) can act as gendisk refcount.
<viro@math.psu.edu>
[PATCH] refcounts for gendisks
Finally. We use disk->dev.refcount as a gendisk refcount. New helper -
get_disk(): atomic_inc on refcount. get_gendisk() does it on return,
callers of get_gendisk() do put_disk() when they are done.
<viro@math.psu.edu>
[PATCH] bdev->bd_disk introduced
There we go - now we can put a reference to gendisk into block_device. Which
we do in do_open(). Most of the callers of get_gendisk() are simply using
bdev->bd_disk now (and most of the put_disk() calls introduced on previous
step disappear). We also put that pointer into struct request - ->rq_disk.
That allows to get rid of disk_index() kludges in md.c (we simply count
relevant IO in the struct gendisk fields) and kill the export of get_gendisk().
Notice that by now we can move _all_ IO counters into gendisk. That
will kill a bunch of per-major arrays and more importantly, allow to merge
sard in clean way. FWIW, we probably could show them as disk/partitions
attributes in driverfs...
<viro@math.psu.edu>
[PATCH] bunch of ->open() killed.
Quite a few drivers don't need ->open() anymore - all it did was checking
that minor is good (== gendisk exists). That is handled by generic code
now...

[PATCH] oprofile - hooks
This implements the simple hooks we need to catch unmappings, and to
make sure no stale task_struct*'s are ever used by the main oprofile
core mechanism. If disabled, it compiles to nothing.
<levon@movementarian.org>
[PATCH] oprofile - dcookies
This implements the persistent path-to-dcookies mapping, and adds a
system call for the user-space profiler to look up the profile data, so
it can tag profiles to specific binaries.
<levon@movementarian.org>
[PATCH] oprofile - timer hook
This implements a simple hook into the profiling timer for x86 so that
non-perfctr machines can still use oprofile. This has proven useful for
laptops and the like.
It also reduces header dependencies a bit by centralising readprofile
code
<levon@movementarian.org>
[PATCH] oprofile - NMI hook
This provides a simple api to let oprofile hook into the NMI interrupt
for the perfctr profiler.
<levon@movementarian.org>
[PATCH] oprofile - MSR defines
Add the MSR defines oprofile uses
<levon@movementarian.org>
[PATCH] oprofile - core
Add the oprofile core. The core design is very similar to that we
discussed in private mail. The nasty details should be documented in
the patch below.
<levon@movementarian.org>
[PATCH] oprofile - i386 driver
Finally, add the i386 timer-interrupt and perfctr drivers for i386
<levon@movementarian.org>
[PATCH] oprofile - dcookies need to use u32
Make dcookies use a stable size regardless of whether we're
on a 32-bit or 64-bit platform.

[PATCH] futex-2.5.42-A2
This is my current futex patchset against BK-curr. It mostly includes
must-have crash/correctness fixes from Martin Wirth, tested and reworked
somewhat by myself:
- crash fix: futex_close did not detach from the vcache. Detach cleanups.
(Martin Wirth)
- memory leak fix: forgotten put_page() in a rare path in __pin_page().
(Martin Wirth)
- crash fix: do not do any quickcheck in unqueue_me(). (Martin, me)
- correctness fix: the fastpath in __pin_page() now handles reserved
pages the same way get_user_pages() does. (Martin Wirth)
- queueing improvement: __attach_vcache() now uses list_add_tail() to
avoid the reversal of the futex queue if a COW happens. (Martin Wirth)
- simplified alignment check in sys_futex. (Martin Wirth)
- comment fix: make it clear how the vcache hash quickcheck works. (me)
<Kai.Makisara@kolumbus.fi>
[PATCH] SCSI tape door lock and reset fixes
- switch to using scsi_ioctl() for drive door locking and unlocking
instead of private code
- use a driver internal flag to save the reset status until tape is

- set driver state properly for all partitions after reset
- change put_device() to driver_unregister() in st_detach()
- C99 initializer changes (from Art Haas)

[PATCH] dpt_i2o TCQ update
This patch for dpt_i2o fixes TCQ stuff, but doesn't solve DMA mapping
issues (so it still doesn't work, but it's not because of TCQ).
Getting around to fixing DMA mapping API issues is much more work per
driver than the TCQ stuff, so I'm putting it off until later.
dpti.h:
Update template
dpt_i2o.c:
Update to new TCQ scheme

[PATCH] Forward port of 2.4 fsync_buffers_list() fix.
there was a bug in fysnc_buffers_list() in 2.4 (fixed in 2.4.19) that
could cause the function to return without having written the current
contents of all the buffers.
Obviously, this could be bad for anybody relying on ordering using
O_SYNC or fsync(). If an I/O was already in flight for a particular bh
at the time of the call to fsync_buffers_list(), ll_rw_block() will not
initiate a new I/O even though the contents may have changed. It is
therefore necessary to wait before the call. Here's a patch against
2.5.42 that applies the same fix.
<peter@chubb.wattle.id.au>
[PATCH] Compile failure (gcc 2.96 bug?). 2.5.42 raid0.c
Yes it's a GCC optimiser bug. I'm surprised I didn't see it: I tried
a whole heap of different compilers on that code, and had problems
only on the earlier similar code in raid0_run().
I didn't try redhat's compilers (I run debian) but didn't expect the
behaviour to be that different.
Anyway, please apply this patch (which also fixes the chunk overlap
problems).

[PATCH] A basic NFSv4 client for 2.5.x
Clean up nfs_fill_super().
Separate the parsing of the nfs_mount_data struct and the
initialization + sanity checking of the resulting super_block.
The latter is now performed in the new function nfs_sb_init().
<trond.myklebust@fys.uio.no>
[PATCH] A basic NFSv4 client for 2.5.x
Further cleanups
Separate the static and dynamic filesystem data retrieval calls as per the
NFSv3 spec. This also simplifies things for NFSv4, since many of the
attributes in the fsinfo+fstat combined call are not mandatory to
implement.
<trond.myklebust@fys.uio.no>
[PATCH] A basic NFSv4 client for 2.5.x
Define the new NFSv4 data structure for passing user information
from the 'mount' program in nfs4_mount.h.
If CONFIG_NFS_V4 is defined
Add code to parse the mount structure into the superblock.
Declare the NFSv4 filesystem to the VFS.
<trond.myklebust@fys.uio.no>
[PATCH] A basic NFSv4 client for 2.5.x
Now that all the hooks are in place, this large patch imports all
of the new code for the NFSv4 client.
nfs4proc.c - procedure vectors
nfs4xdr.c - XDR
nfs4state.c - state bookkeeping (very minimal for now)
nfs4renewd.c - a daemon (implemented as an rpc_task) to keep
state from expiring on the server
Note: The RPCSEC_GSS authentication code is not yet included here.
For the moment we make do with AUTH_UNIX aka. AUTH_SYS.
Neither is the code to do upcalls to userland in order to do
uid/gid <-> name mappings. Instead, stubs have been added to
translate everything to 'nobody:nobody' == '-2:-2'
<trond.myklebust@fys.uio.no>

[PATCH] Summit: config options and hooks
This just adds the config option for summit, and it's Config.help entry,
puts the hooks for the new mach_apic.h subarch file into the right
places, and creates empty shells of the header files.
<Martin.Bligh@us.ibm.com>
[PATCH] Summit: infrastructure
This puts the DFR (desination format register) value into a #define, and
calculates the LDR (logical desitination register) correctly dependant
on platform. Similarly for TARGET_CPUS.
<Martin.Bligh@us.ibm.com>
[PATCH] Summit: APIC limits
This one sets up the apic broadcast id (the maximum allowable apic address)
properly for whichever platform. It also abstracts out check_apicid_used,
because that check doesn't work on Summit. Oh, and I bumped up
MAX_IO_APICS, but only for NUMA x86 platforms.
<Martin.Bligh@us.ibm.com>
[PATCH] Summit: MPS table detection
Adds detection for summit machines from the MPS tables.
Prints a handy-dandy debug message telling you what kind of twisted
machine the kernel thinks you have.
<Martin.Bligh@us.ibm.com>
[PATCH] Summit: APIC ID mapping
Adds a raw_phys_apicid array that maps from the mps cpu number
to the apicid - this is needed because the apicids for Summit can be
larger than 32, and thus won't fit into the bitmap. Also adds little wrappers
to map neatly between the two.
Bumps up MAX_APICS for Summit.
<dipankar@in.ibm.com>
[PATCH] Read-Copy Update infrastructure
This is the RCU core patch from akpm's tree. It has been in his
tree since about 2.5.37-mm1 along with dcache_rcu and so far it has
worked fine. For 2.5, I am hoping that we might get the following
RCU patches included -
1. rt_rcu - ipv4 routecache lookup. Davem agreed to include this patch
if and when you include RCU core in your tree.
2. dcache_rcu (by Maneesh Soni) - dcache lookup avoiding dcache_lock as
much as possible. This has been akpm's tree - stable and gives us
good yield. I have been submitting this to Viro and I will publish
some more benchmark numbers later to help decide on this.
This RCU core implements RCU APIs, call_rcu() and synchronize_kernel(),
by monitoring a per-CPU quiescent state (idle/user etc.) counter.
call_rcu() queues a callback to be invoked after all the CPUs have
gone through a quiescent state. Queuing is per-CPU and each per-CPU
batch gets a batch number. As batches get their turn, a global
cpu mask is used to keep track of CPUs pending quiescent state.
Checking for quiescent cycle is done by saving the per-CPU
counter at the beginning of the batch and then monitoring it for change
through the local timer interrupt handler.

[PATCH] Small PCMCIA patch
