9 patches for md in 2.6.11-rc3-mm2 follow.
1 - tightens up some locking to close a race that is extremely unlikely
to happen (famous last words). It can only happen when failed devices are
being removed.
2 - Fixes a resync related problem for raid5 and raid6 arrays that have
lost more devices than they can cope with.
3 - Fixes a clumsy test that has very little real effect (just a printk).
These three can be considered stable.
4,5 Improve handling of 'safemode' which is where we mark the superblock
clean whenever there have been no writes for a little while, and mark
it dirty before the next write.
6-9 Introduce "bitmap based intent logging" which allows a file to
store - as a bitmap - all block that may have been written recently.
This allow resync to be optimised, which is more important as drives
get larger.
These should not be considerred stable - certainly actually using
the bitmap mode (which requires a 2.0 series version of mdadm) should
be seen as 'experimental'.
mdadm-2.0-devel-1 was released today.
