#     Merge tag 'for-5.11/dm-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
#     
#     Pull device mapper fixes from Mike Snitzer:
#     
#      - Fix DM-raid's raid1 discard limits so discards work.
#     
#      - Select missing Kconfig dependencies for DM integrity and zoned
#        targets.
#     
#      - Four fixes for DM crypt target's support to optionally bypass kcryptd
#        workqueues.
#     
#      - Fix DM snapshot merge supports missing data flushes before committing
#        metadata.
#     
#      - Fix DM integrity data device flushing when external metadata is used.
#     
#      - Fix DM integrity's maximum number of supported constructor arguments
#        that user can request when creating an integrity device.
#     
#      - Eliminate DM core ioctl logging noise when an ioctl is issued without
#        required CAP_SYS_RAWIO permission.
