dm: avoid filesystem lookup in dm_get_dev_t() (2021-01-21 15:06:45 -0500)

Please pull, thanks.

----------------------------------------------------------------
- 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).
