The current 2.6 prepatch is 2.6.24-rc4
by Linus on
December 3. He says that the size of the patch is "a bit
disheartening," and, in fact, there are quite a few changes which have been
merged. They are almost all fixes, but there also the addition of a CPU
accounting controller for monitoring the CPU usage of groups of processes. See the short-form changelog
for the details, or
for lots of details.
As of this writing, just under 100 changesets have gone into the mainline
repository since the -rc4 release.
The current -mm tree is 2.6.24-rc4-mm1. Recent changes
to -mm include the latest timerfd
API, a new memory controller patch, and a reimplemented ramdisk driver.
