Hi Linus,
Some changes were slightly late and their inclusion made later because
I had a worse-than-expected reaction to my 2nd covid shot the past
couple days. Nothing crazy here but wanted to explain why some commits
are recent.
The following changes since commit 4edbe1d7bcffcd6269f3b5eb63f710393ff2ec7a:
dm ioctl: fix out of bounds array access when no devices (2021-03-26 14:51:50 -0400)
are available in the Git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git tags/for-5.13/dm-changes
for you to fetch changes up to ca4a4e9a55beeb138bb06e3867f5e486da896d44:
dm raid: remove unnecessary discard limits for raid0 and raid10 (2021-04-30 14:38:37 -0400)
Please pull, thanks.
Mike
----------------------------------------------------------------
- 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.
