The current 2.6 prepatch remains 2.6.9-rc1
; no new prepatches have
been released since August 24.
The flow of patches into Linus's BitKeeper repository continues, however,
and a new prepatch could come out at any time. That repository now
contains the removal of the ancient, unused "busmouse" driver,
infrastructure for cluster-wide file locking, a number of DRM subsystem
cleanups, the out-of-line spinlock patch,
AMD dual-core support, more filesystem conversions to the new
symbolic link resolution code (which will eventually allow an increase in
the maximum link depth), a new waitid() system call implementing
the POSIX call by the same name, a "fake NUMA" mode for x86-64 testing, a
small-footprint tmpfs implementation, the base KProbes patch, a
set of IDE updates, support for scheduler profiling (seeing where context
switches come from), automatic TCP window scaling calculation, a kobject
change (it uses kref now), a USB gadget interface update with "On The Go"
support, a big ALSA update, the removal of the Philips webcam driver,
numerous network driver updates, some random number generator fixes, a fix
for the audio CD writing memory leak, some VFS interface improvements,
executable support in hugetlb mappings, the Whirlpool digest algorithm,
some virtual memory tweaks, a number of asynchronous I/O fixes and
improvements, a User-mode Linux update, the "flex mmap" user-space memory
layout (covered here last
June), a number of scheduler tweaks, the removal of the very last
suser() call, and lots of fixes.
The current tree from Andrew Morton is 2.6.9-rc1-mm4. Recent changes to -mm
include CacheFS (covered here last week),
the removal of lockmeter (it got broken by the out-of-line spinlock patch),
special code for handling misrouted interrupts on x86 systems, the new
sysfs event layer patch (see below), and M32R architecture support.
The current 2.4 prepatch remains 2.4.28-pre2; no prepatches have
been released since August 25.
