Merge tag 'for-6.6/dm-fixes' of git://git./linux/kernel/git/device-mapper/linux-dm

Pull device mapper fixes from Mike Snitzer:

 - Fix DM core retrieve_deps() UAF race due to missing locking of a DM
   table's list of devices that is managed using dm_{get,put}_device.

 - Revert DM core's half-baked RCU optimization if IO submitter has set
   REQ_NOWAIT. Can be revisited, and properly justified, after
   comprehensively auditing all of DM to also pass GFP_NOWAIT for any
   allocations if REQ_NOWAIT used.

* tag 'for-6.6/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
  dm: don't attempt to queue IO under RCU protection
  dm: fix a race condition in retrieve_deps
