Kernel release status
The current 2.6 kernel is 2.6.7, which was announced by Linus on June 15. Changes
since the last release candidate include a fix for the latest denial of
service vulnerability (see below), an NTFS update, some more CPU frequency
controller work, and lots of fixes. The biggest changes since 2.6.6
include scheduling domains, a big rework of
the reverse-mapping VM code, filtered waitqueues, the removal of the
InterMezzo filesystem, quota and extended attribute support in reiserfs, a
new API for NUMA systems, the removal of IDE tagged command queueing
support, and the usual pile of fixes. See the
long-format changelog for the details.
Linus's BitKeeper repository contains no patches beyond 2.6.7 as of this writing.
The current tree from Andrew Morton is 2.6.7-rc3-mm2. Recent additions to -mm include ext3 resizing support (see below), a O_NOATIME option to open(), and various fixes.
The current 2.4 prepatch is 2.4.27-pre6, which was released on June 15. It
includes the FPU denial of service fix, of course, along with some
architecture updates, DVD-RW write support, and a fair number of fixes.
