Kernel release status

Linus's BitKeeper tree contains, as of this writing, an important workqueue fix (it seems nobody had actually tried to use cancel_delayed_work() until now...), an updated MTD concatenating driver, several architecture updates, and lots of fixes.

The current tree from Andrew Morton is 2.6.6-rc3-mm2. Recent additions to the -mm tree include another set of reverse mapping VM patches from Hugh Dickins, a new ia_64 hotplug CPU patch set, a patch to enable interrupts while waiting on spinlocks, the permanent abolition of 8K stacks on the x86 architecture, a new /proc/sys/kernel/vermagic file to enable package installers to figure out how the kernel was built, filtered sleeps and wakeups (see below), a new NUMA API, and, of course, lots of fixes.

Andrew indicates that the scheduling domains patches are being fixed up and prepared for merging once 2.6.6 is released. He also plans to merge a number of the reverse mapping VM patches, including the anonmm work, even though the final decision on whether to go that way or with the rival anon_vma technique has not yet been made.

The current 2.4 prepatch is 2.4.27-pre2, which was released by Marcelo on May 3. Changes this time include some crypto updates, some XFS fixes, various networking updates, and a handful of other fixes.
