The bulk of this update is changes to allow md/raid5 to be plugged into dm as a dm target. The changes to dm to make this happen are with the dm maintainer who has given in-principle agreement - they just need to be carefully reviewed. The remainder are some deadlock fixes which are tagged for -stable, one of which should have been around for quite some time, but have only manifested recently for some strange reason.
