"Extended discard support means that Linux now supports ATA
TRIM, which can increase SSD lifespan and throughput. New additions
to the Linux kernel include HA solution DRBD and drivers for HP,
LSI and VMware storage hardware. The new kernel version, expected
in early March, also includes many minor improvements to the code
for the Btrfs, Ext4 and ReiserFS file systems.
"At the end of last week, Linus Torvalds released the fifth
pre-release version of Linux version 2.6.33, with the final release
expected in 4 to 5 weeks time. At this stage in the development
cycle, it is usually predominantly more minor changes and fixes
which find their way into the main development tree. Kernel hackers
do, however, make occasional exceptions for drivers. Linux
2.6.33-rc5 sees the addition to the kernel of a V4L/DVB driver
which supports the Mantis chip-set used in a range of TV cards.
However, the changes to the V4L/DVB subsystem in Linux 2.6.33 are
the subject of a future article in the "Coming in 2.6.33"
"Following on from the first article in the 2.6.33 series, which
looked at networking changes, this article examines file systems
changes and changes to the kernel's storage subsystem."
