  dm: don't attempt to queue IO under RCU protection (2023-09-15 15:39:59 -0400)

Please pull, thanks.

----------------------------------------------------------------
- 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.
