- 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.
dm raid: remove unnecessary discard limits for raid0 and raid10
Commit 29efc390b946 ("md/md0: optimize raid0 discard handling") and
commit d30588b2731f ("md/raid10: improve raid10 discard request")
remove MD raid0's and raid10's inability to properly handle large
discards. So eliminate associated constraints from dm-raid's support.
