Kernel release status

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.
