# commit fe75a21824e78405b8d812421974524092250c63
# Merge: faba877b3bcc 809b1e494577
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Fri Jan 22 14:31:00 2021 -0800

#     Merge tag 'for-5.11/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
#     
#     Pull device mapper fixes from Mike Snitzer:
#     
#      - Fix DM integrity crash if "recalculate" used without "internal_hash"
#     
#      - Fix DM integrity "recalculate" support to prevent recalculating
#        checksums if we use internal_hash or journal_hash with a key (e.g.
#        HMAC). Use of crypto as a means to prevent malicious corruption
#        requires further changes and was never a design goal for
#        dm-integrity's primary usecase of detecting accidental corruption.
#     
#      - Fix a benign dm-crypt copy-and-paste bug introduced as part of a fix
#        that was merged for 5.11-rc4.
#     
#      - Fix DM core's dm_get_device() to avoid filesystem lookup to get block
#        device (if possible).

#       dm crypt: fix copy and paste bug in crypt_alloc_req_aead
#       dm integrity: conditionally disable "recalculate" feature
#       dm integrity: fix a crash if "recalculate" used without "internal_hash"
