The current development kernel is 2.5.72
, which was released
by Linus on June 16. This
relatively small patch contains an x86-64 merge, a partial reversion of the
IDE taskfile switchover, a PA-RISC update, and various fixes and cleanups.
The long-format changelog
has the details.
Linus had released the 2.5.71 ("sticky
turtle") kernel only two days before. This long-awaited patch included a
fair amount of driver model work, some extensive PCI bus cleanups (dealing
with potential race conditions there), the big IDE changeover to taskfile
I/O, a new /proc/kallsyms file, support for per-CPU variables in
modules, a change the kmalloc_percpu() interface, an Atmel
at76c50x wireless driver, a long-sought fix for hanging TCP sessions, an
improved slab allocator which performs better in busy, multi-processor
situations, some kbuild tweaks, an ALSA update, a set of hash function
changes to deal with algorithmic complexity attacks, a FAT filesystem
rework (if you have been waiting to be able to create FAT partitions
greater than 128GB, this patch is for you), a v850 subarchitecture merge, a
RAID update, the removal of the long-deprecated callout TTY device
(/dev/cua) support, numerous architecture updates, and several
other fixes and updates. As always, the
long-format changelog has the gory details.
Linus's BitKeeper tree contains an extensive ext3 and JBD rework (see
below), an OProfile update, some NFS server fixes, and a few other fixes
With the 2.5.72 announcement, Linus announced that he is taking a leave of
absence from Transmeta to go work at the Open Source Development Lab.
"Transmeta has always been very good at letting me spend even an
inordinate amount of time on Linux, but as a result I've been feeling a
little guilty at just how little 'real work' I got done lately. To fix
that, I'll instead be working at OSDL, finally actually doing Linux as my
The current stable kernel is 2.4.21, released, at last, on June 13. There were
no changes since -rc8.
No 2.4.22 prepatches have come out yet. Marcelo's plan, at this point, is to have 2.4.22 contain
an updated aic7xx driver and the current ACPI tree (both items that people
had wanted in 2.4.21), along with some interactivity and memory management
