    Merge tag 'for-5.12/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
    
    Pull device mapper updates from Mike Snitzer:
    
     - Fix DM integrity's HMAC support to provide enhanced security of
       internal_hash and journal_mac capabilities.
    
     - Various DM writecache fixes to address performance, fix table output
       to match what was provided at table creation, fix writing beyond end
       of device when shrinking underlying data device, and a couple other
       small cleanups.
    
     - Add DM crypt support for using trusted keys.
    
     - Fix deadlock when swapping to DM crypt device by throttling number of
       in-flight REQ_SWAP bios. Implemented in DM core so that other
       bio-based targets can opt-in by setting ti->limit_swap_bios.
    
     - Fix various inverted logic bugs in the .iterate_devices callout
       functions that are used to assess if specific feature or capability
       is supported across all devices being combined/stacked by DM.
    
     - Fix DM era target bugs that exposed users to lost writes or memory
       leaks.
    
     - Add DM core support for passing through inline crypto support of
       underlying devices. Includes block/keyslot-manager changes that
       enable extending this support to DM.
    
     - Various small fixes and cleanups (spelling fixes, front padding
       calculation cleanup, cleanup conditional zoned support in targets,
       etc).
