#     Merge tag 'for-5.3/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
#     
#     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.
#
