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.
