Hi Linus,
These DM changes happen to be based on linux-block from a few weeks ago
(but an expected DM dependency on block turned out to not be needed).
And the few block/keyslot-manager changes are accompanied by Jens'
Acked-by.
The following changes since commit 8358c28a5d44bf0223a55a2334086c3707bb4185:
block: fix memory leak of bvec (2021-02-02 08:57:56 -0700)

dm: fix deadlock when swapping to encrypted device (2021-02-11 09:45:28 -0500)
Please pull, thanks.
Mike
----------------------------------------------------------------
- Fix DM integrity's HMAC support to provide enhanced security of
internal_hash and journal_mac capabilities.
- Various DM writecache fixes to address performance, fix table output
to match what was provided at table creation, fix writing beyond end
of device when shrinking underlying data device, and a couple other
small cleanups.
- Add DM crypt support for using trusted keys.
- Fix deadlock when swapping to DM crypt device by throttling number
of in-flight REQ_SWAP bios. Implemented in DM core so that other
bio-based targets can opt-in by setting ti->limit_swap_bios.
- Fix various inverted logic bugs in the .iterate_devices callout
functions that are used to assess if specific feature or capability
is supported across all devices being combined/stacked by DM.
- Fix DM era target bugs that exposed users to lost writes or memory
leaks.
- Add DM core support for passing through inline crypto support of
underlying devices. Includes block/keyslot-manager changes that
enable extending this support to DM.
- Various small fixes and cleanups (spelling fixes, front padding
calculation cleanup, cleanup conditional zoned support in targets,
etc).
