Hi Linus,
The following changes since commit 7e768532b2396bcb7fbf6f82384b85c0f1d2f197:
dm snapshot: properly fix a crash when an origin has no snapshots (2021-05-25 16:19:58 -0400)
are available in the Git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git tags/for-5.14/dm-changes

dm writecache: make writeback pause configurable (2021-06-28 16:30:13 -0400)
Please pull, thanks.
Mike
----------------------------------------------------------------
- Various DM persistent-data library improvements and fixes that
benefit both the DM thinp and cache targets.
- A few small DM kcopyd efficiency improvements.
- Significant zoned related block core, DM core and DM zoned target
changes that culminate with adding zoned append emulation (which is
required to properly fix DM crypt's zoned support).
- Various DM writecache target changes that improve efficiency. Adds
an optional "metadata_only" feature that only promotes bios flagged
with REQ_META. But the most significant improvement is writecache's
ability to pause writeback, for a confiurable time, if/when the
working set is larger than the cache (and the cache is full) -- this
ensures performance is no worse than the slower origin device.
----------------------------------------------------------------
Baokun Li (1):
dm writecache: use list_move instead of list_del/list_add in writecache_writeback()
Colin Ian King (1):
dm ps io affinity: remove redundant continue statement
Damien Le Moal (13):
dm zoned: check zone capacity
dm: Fix dm_accept_partial_bio() relative to zone management commands
dm: cleanup device_area_is_invalid()
dm: move zone related code to dm-zone.c
dm: Introduce dm_report_zones()
dm: Forbid requeue of writes to zones
block: improve handling of all zones reset operation
block: introduce bio zone helpers
block: introduce BIO_ZONE_WRITE_LOCKED bio flag
dm: rearrange core declarations for extended use from dm-zone.c
dm: introduce zone append emulation
dm crypt: Fix zoned block device support
dm zone: fix dm_revalidate_zones() memory allocation
Hou Tao (1):
dm btree remove: assign new_root only when removal succeeds
Joe Thornber (4):
dm btree: improve btree residency
dm space maps: don't reset space map allocation cursor when committing
dm space maps: improve performance with inc/dec on ranges of blocks
dm space map disk: cache a small number of index entries
Mike Snitzer (2):
dm writecache: add "cleaner" and "max_age" to Documentation
dm io tracker: factor out IO tracker
Mikulas Patocka (12):
dm kcopyd: avoid useless atomic operations
dm kcopyd: avoid spin_lock_irqsave from process context
dm writecache: don't split bios when overwriting contiguous cache content
dm writecache: interrupt writeback if suspended
dm writecache: remove unused gfp_t argument from wc_add_block()
dm writecache: commit just one block, not a full page
dm writecache: have ssd writeback wait if the kcopyd workqueue is busy
dm writecache: flush origin device when writing and cache is full
dm writecache: write at least 4k when committing
dm writecache: add optional "metadata_only" parameter
