Linus Torvalds e39bfb5925 - 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.
