The first release candidate for the
Linux 2.6.29 kernel is now available. The Linux 2.6.29 kernel features
kernel mode-setting support (only on Intel hardware, currently), the
Btrfs file-system, and a number of new drivers and updates to others. Besides Btrfs entering the kernel, the SquashFS compressed read-only file-system has entered the kernel as well.
