2021-08-10	dm writecache: add event counters	Mikulas Patocka
	Add 10 counters for various events (hit, miss, etc) and export them in the status line (accessed from userspace with "dmsetup status"). Also add a message "clear_stats" that resets these counters. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
2021-06-28	dm writecache: make writeback pause configurable	Mikulas Patocka
	Commit 95b88f4d71cb953e02206be3c757083601391a0f ("dm writecache: pause writeback if cache full and origin being written directly") introduced a code that pauses cache flushing if we are issuing writes directly to the origin. Improve that initial commit by making the timeout code configurable (via the option "pause_writeback"). Also change the default from 1s to 3s because it performed better.

2021-06-25	dm writecache: add optional "metadata_only" parameter	Mikulas Patocka
	Add a "metadata_only" parameter that when present: only metadata is promoted to the cache. This option improves performance for heavier REQ_META workloads (e.g. device-mapper-test-suite's "git clone and checkout" benchmark improves from 341s to 312s).
