Merge tag 'for-6.4/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

Pull device mapper updates from Mike Snitzer:

- Split dm-bufio's rw_semaphore and rbtree. Offers improvements to
dm-bufio's locking to allow increased concurrent IO -- particularly
for read access for buffers already in dm-bufio's cache.

- Also split dm-bio-prison-v1's spinlock and rbtree with comparable aim
at improving concurrent IO (for the DM thinp target).

- Both the dm-bufio and dm-bio-prison-v1 scaling of the number of locks
and rbtrees used are managed by dm_num_hash_locks(). And the hash
function used by both is dm_hash_locks_index().

- Allow DM targets to require DISCARD, WRITE_ZEROES and SECURE_ERASE to
be split at the target specified boundary (in terms of
max_discard_sectors, max_write_zeroes_sectors and
max_secure_erase_sectors respectively).

- DM verity error handling fix for check_at_most_once on FEC.

- Update DM verity target to emit audit events on verification failure
and more.

- DM core ->io_hints improvements needed in support of new discard
support that is added to the DM "zero" and "error" targets.

- Fix missing kmem_cache_destroy() call in initialization error path of
both the DM integrity and DM clone targets.

- A couple fixes for DM flakey, also add "error_reads" feature.

- Fix DM core's resume to not lock FS when the DM map is NULL;
otherwise initial table load can race with FS mount that takes
superblock's ->s_umount rw_semaphore.

- Various small improvements to both DM core and DM targets.

dm: improve hash_locks sizing and hash function

Both bufio and bio-prison-v1 use the identical model for splitting
their respective locks and rbtrees. Improve dm_num_hash_locks() to
distribute across more rbtrees to improve overall performance -- but
the maximum number of locks/rbtrees is still 64.

Also factor out a common hash function named dm_hash_locks_index(),
the magic numbers used were determined to be best using this program:

dm bio prison v1: add dm_cell_key_has_valid_range

Don't have bio_detain() BUG_ON if a dm_cell_key is beyond
BIO_PRISON_MAX_RANGE or spans a boundary.

Update dm-thin.c:build_key() to use dm_cell_key_has_valid_range() which
will do this checking without using BUG_ON. Also update
process_discard_bio() to check the discard bio that DM core passes in
(having first imposed max_discard_granularity based splitting).

dm_cell_key_has_valid_range() will merely WARN_ON_ONCE if it returns
false because if it does: it is programmer error that should be caught
with proper testing. So relax the BUG_ONs to be WARN_ON_ONCE.

dm bio prison v1: improve concurrent IO performance

Split the bio prison into multiple regions, with a separate rbtree and
associated lock for each region.

To get fast bio prison locking and not damage the performance of
discards too much the bio-prison now stipulates that discards should
not cross a BIO_PRISON_MAX_RANGE boundary.

Because the range of a key (block_end - block_begin) must not exceed
BIO_PRISON_MAX_RANGE: break_up_discard_bio() now ensures the data
range reflected in PHYSICAL key doesn't exceed BIO_PRISON_MAX_RANGE.
And splitting the thin target's discards (handled with VIRTUAL key) is
achieved by updating dm-thin.c to set limits->max_discard_sectors in
terms of BIO_PRISON_MAX_RANGE _and_ setting the thin and thin-pool
targets' max_discard_granularity to true.

Merge tag 'for-6.3/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

Pull device mapper updates from Mike Snitzer:

- Fix DM cache target to free background tracker work items, otherwise
slab BUG will occur when kmem_cache_destroy() is called.

- Improve 2 of DM's shrinker names to reflect their use.

- Fix the DM flakey target to not corrupt the zero page. Fix dm-flakey
on 32-bit hughmem systems by using bvec_kmap_local instead of
page_address. Also, fix logic used when imposing the
"corrupt_bio_byte" feature.

- Stop using WQ_UNBOUND for DM verity target's verify_wq because it
causes significant Android latencies on ARM64 (and doesn't show real
benefit on other architectures).

- Add negative check to catch simple case of a DM table referencing
itself. More complex scenarios that use intermediate devices to
self-reference still need to be avoided/handled in userspace.

- Fix DM core's resize to only send one uevent instead of two. This
fixes a race with udev, that if udev wins, will cause udev to miss
uevents (which caused premature unmount attempts by systemd).

- Add cond_resched() to workqueue functions in DM core, dn-thin and
dm-cache so that their loops aren't the cause of unintended cpu
scheduling fairness issues.

- Fix all of DM's checkpatch errors and warnings (famous last words).
Various other small cleanups.
