The current 2.6 prepatch is 2.6.16-rc4
by Linus on
February 17. Things are settling down, and this prepatch contains
"only" 100 fixes or so, many concentrated in the SCSI subsystem. Details
can be found in the long-format changelog
As of this writing, the mainline git repository contains about 75 post-rc4
patches, including one reverting a change which broke systems running
non-current versions of HAL (see below).
The current -mm tree is 2.6.16-rc4-mm1. Recent changes
to -mm include the addition of Al Viro's "bird" tree, a big x86-64 update,
some memory management tweaks, some software suspend patches, a big
"generic bit operations" patch set, and the lightweight robust futex patch.
For 2.4 users, Marcelo has released the second 2.4.33 prepatch with
several fixes, some of which are security-related.
