Merge tag 'for-5.4/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper updates from Mike Snitzer:
- crypto and DM crypt advances that allow the crypto API to reclaim
implementation details that do not belong in DM crypt. The wrapper
template for ESSIV generation that was factored out will also be used
by fscrypt in the future.
- Add root hash pkcs#7 signature verification to the DM verity target.
- Add a new "clone" DM target that allows for efficient remote
replication of a device.
- Enhance DM bufio's cache to be tailored to each client based on use.
Clients that make heavy use of the cache get more of it, and those
that use less have reduced cache usage.
- Add a new DM_GET_TARGET_VERSION ioctl to allow userspace to query the
version number of a DM target (even if the associated module isn't
yet loaded).
- Fix invalid memory access in DM zoned target.
- Fix the max_discard_sectors limit advertised by the DM raid target;
it was mistakenly storing the limit in bytes rather than sectors.
- Small optimizations and cleanups in DM writecache target.
- Various fixes and cleanups in DM core, DM raid1 and space map portion
of DM persistent data library.
