#     Merge tag 'for-5.7/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
#     
#     Pull device mapper fixes from Mike Snitzer:
#     
#      - Document DM integrity allow_discard feature that was added during 5.7
#        merge window.
#     
#      - Fix potential for DM writecache data corruption during DM table
#        reloads.
#     
#      - Fix DM verity's FEC support's hash block number calculation in
#        verity_fec_decode().
#     
#      - Fix bio-based DM multipath crash due to use of stale copy of
#        MPATHF_QUEUE_IO flag state in __map_bio().
#     
#     * tag 'for-5.7/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
#       dm multipath: use updated MPATHF_QUEUE_IO on mapping for bio-based mpath
#       dm verity fec: fix hash block number in verity_fec_decode
