(Stable Linux 2.6.32) 



Linus Torvalds announced the release of a stable Linux 2.6.32 kernel. 

Major additions include kernel-based mode setting (KMS) and

3D graphics support on select Radeon cards, plus new kernel shared memory (KSM) 

technology for KVM virtualization, power-saving

and performance improvements, and a faster "Devtmpfs" boot technology.

Many of the recent Linux kernel releases have focused on filesystems, such as September's Linux 2.6.31, which was notable primarily

for adding USB 3.0 support, but also offered a much more robust implementation of the Btrfs filesystem. Before that, Linux 2.6.30 added

the NILFS2, EXOFS, and POHMELFS filesystems, and Linux 2.6.29 debuted the embedded-oriented Squashfs filesystem, as well as

the first implementation of Btrfs.

With Linux 2.6.32, however, "I think we have a release without any actual new filesystem for once," writes Torvalds (pictured at top) in

the announcement. "But there's been a fair amount of changes to btrfs, and the block layer writeback itself has been through major

updates, and the whole per-bdi writeback thing is a pretty big change. Other rather noticeable changes are in . . . drivers all over the
