Kernel release status

The developers have been busy, however. Linus's BitKeeper repository contains, as of this writing, 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-mm2. Recent changes to -mm include some scheduler fixes (Nick Piggins's scheduler is still in -mm), the removal of the resident set size limit ("pending some evidence that it does useful things"), the out-of-line spinlocks patch (for x86 and x86-64), lockmeter for x86-64, and many fixes and updates.

The current 2.4 prepatch is 2.4.28-pre2, released by Marcelo on August 25. Changes include a serial ATA update, some gcc-3.4 fixes, an NFS update, and various other fixes.
