Hello,

The 1st patch removes blk_freeze_queue().

The 2nd patch fixes freeze uses in rbd.

The 3rd patches fixes potential unfreeze lock verification on non-owner
context.

The 4th patch doesn't verify io lock in elevator_init_mq() for fixing
false lockdep warning.

V2:
	- drop patch 1 and fix rbd by adding unfreeze (Christoph)
	- add reviewed-by


Ming Lei (4):
  block: remove blk_freeze_queue()
  rbd: unfreeze queue after marking disk as dead
  block: always verify unfreeze lock on the owner task
  block: don't verify IO lock for freeze/unfreeze in elevator_init_mq()
