Op de Linux Kernel Mailing List is een nieuwe Linux 2.6-kernel aangekondigd. De kernel is ditmaal aangekomen bij versienummer 2.6.32.3. De veranderingen zijn uitvoerig toegelicht in het changelog. De update heeft geen eigen versienummer en uitgebreide aankondiging gekregen, maar het is de derde update van versie 2.6.32 van de kernel. Die versie werd begin december aangekondigd door Linus Torvalds en bevat een aantal verbeteringen ten opzichte van 2.6.31, die Torvalds toelicht in zijn mail:
Linux 2.6.32
This release _feels_ long overdue due to two empty weeks for me (kernel
summit and thanksgiving week vacation), but it's actually less than three
months since 2.6.31, so I guess it's actually not that far off the normal
schedule.
I've been merging a few things that were pending while I was offline, but
it really seems to have been pretty quiet. The biggest thing since -rc8
is the horribly timed stability fixes for fscache, which caused some
hickups and I really wish it hadn't happened that way, but apart from that
it's mainly small updates (and mainly drivers).
The dirstat from -rc8 looks like
2.7% arch/blackfin/
5.8% arch/
2.1% drivers/misc/eeprom/
3.5% drivers/net/e1000e/
9.6% drivers/net/
3.9% drivers/staging/
2.0% drivers/usb/musb/
2.8% drivers/usb/
34.8% drivers/
4.1% fs/cachefiles/
24.9% fs/fscache/
32.6% fs/
14.5% kernel/
3.7% net/
and that fs/ and kernel/ noise is mostly from that fscache thing (the
kernel subdirectory part is the "slow-work" stuff that fscache uses), and
the shortlog is appended.
As to the "big feature" changes in 2.6.32 since 31 - I think we have a
release without any actual new filesystem for once, 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 KSM (both intel and radeon) and in
drivers all over the place. As usual, kernelnewbies (and other sites, for
that matter) has more details for people who want to delve into it all by
subsystem.
