Merge tag 'for-5.13/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper updates from Mike Snitzer: - Improve scalability of DM's device hash by switching to rbtree - Extend DM ioctl's DM_LIST_DEVICES_CMD handling to include UUID and allow filtering based on name or UUID prefix. - Various small fixes for typos, warnings, unused function, or needlessly exported interfaces. - Remove needless request_queue NULL pointer checks in DM thin and cache targets. - Remove unnecessary loop in DM core's __split_and_process_bio(). - Remove DM core's dm_vcalloc() and just use kvcalloc or kvmalloc_array instead (depending whether zeroing is useful). - Fix request-based DM's double free of blk_mq_tag_set in device remove after table load fails. - Improve DM persistent data performance on non-x86 by fixing packed structs to have a stated alignment. Also remove needless extra work from redundant calls to sm_disk_get_nr_free() and a paranoid BUG_ON() that caused duplicate checksum calculation. - Fix missing goto in DM integrity's bitmap_flush_interval error handling. - Add "reset_recalculate" feature flag to DM integrity. - Improve DM integrity by leveraging discard support to avoid needless re-writing of metadata and also use discard support to improve hash recalculation. - Fix race with DM raid target's reshape and MD raid4/5/6 resync that resulted in inconsistant reshape state during table reloads. - Update DM raid target to temove unnecessary discard limits for raid0 and raid10 now that MD has optimized discard handling for both raid levels. * tag 'for-5.13/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (26 commits) dm raid: remove unnecessary discard limits for raid0 and raid10 dm rq: fix double free of blk_mq_tag_set in dev remove after table load fails dm integrity: use discard support when recalculating dm integrity: increase RECALC_SECTORS to improve recalculate speed dm integrity: don't re-write metadata if discarding same blocks dm raid: fix inconclusive reshape layout on fast raid4/5/6 table reload sequences dm raid: fix fall-through warning in rs_check_takeover() for Clang dm clone metadata: remove unused function dm integrity: fix missing goto in bitmap_flush_interval error handling dm: replace dm_vcalloc() dm space map common: fix division bug in sm_ll_find_free_block() dm persistent data: packed struct should have an aligned() attribute too dm btree spine: remove paranoid node_check call in node_prep_for_write() dm space map disk: remove redundant calls to sm_disk_get_nr_free() dm integrity: add the "reset_recalculate" feature flag dm persistent data: remove unused return from exit_shadow_spine() dm cache: remove needless request_queue NULL pointer checks dm thin: remove needless request_queue NULL pointer check dm: unexport dm_{get,put}_table_device dm ebs: fix a few typos ...
