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. * tag 'for-5.4/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (22 commits) dm: introduce DM_GET_TARGET_VERSION dm bufio: introduce a global cache replacement dm bufio: remove old-style buffer cleanup dm bufio: introduce a global queue dm bufio: refactor adjust_total_allocated dm bufio: call adjust_total_allocated from __link_buffer and __unlink_buffer dm: add clone target dm raid: fix updating of max_discard_sectors limit dm writecache: skip writecache_wait for pmem mode dm stats: use struct_size() helper dm crypt: omit parsing of the encapsulated cipher dm crypt: switch to ESSIV crypto API template crypto: essiv - create wrapper template for ESSIV generation dm space map common: remove check for impossible sm_find_free() return value dm raid1: use struct_size() with kzalloc() dm writecache: optimize performance by sorting the blocks for writeback_all dm writecache: add unlikely for getting two block with same LBA dm writecache: remove unused member pointer in writeback_struct dm zoned: fix invalid memory access dm verity: add root hash pkcs#7 signature verification ...
