This series of raid patches critically fixes:
- a race causing hangs occuring on tiny devices
- a reshape deadlock / potential data corruption
- a superblock update problem rebuilding individual component devices
In addition, it contains (patches 4+5, less critical) removal
of code duplication deciphering the synchonization action and
avoids to create a bitmap when using a raid4/5/6 journal device.
Fixes pass all lvm2 raid tests.
Heinz Mauelshagen (5):
dm-raid: fix reshape race on small devices
dm-raid: fix stripe adding reshape deadlock
dm-raid: correct explicit superblock update requests
dm-raid: share decipher_sync_action
dm-raid: disable bitmap when journaled
