Subject: [PATCH 0/5] dm raid: deadlock/corruptor fixes
Date: Wed,  5 Sep 2018 19:36:40 +0200	[thread overview]
Message-ID: <cover.1536167421.git.heinzm@redhat.com> (raw)

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
