Pull device mapper fixes from Mike Snitzer:

 - Revert a DM bufio change from during the 5.3 merge window now that a
   proper fix has been made to the block loopback driver.

 - Fix DM kcopyd to wakeup so failed subjobs get completed.

 - Various fixes to DM zoned target to address error handling, and other
   small tweaks (SPDX license identifiers and fix typos).

 - Fix DM integrity range locking race by tracking whether journal has
   changed.

 - Fix DM dust target to detect reads of badblocks beyond the first 512b
   sector (applicable if blocksize is larger than 512b).

 - Fix DM persistent-data issue in both the DM btree and DM
   space-map-metadata interfaces.

 - Fix out of bounds memory access with certain DM table configurations.
