Hi Linus,

When I sent my pull last Friday I had overlooked some email that Nikos
(cc'd) sent that same morning concerning review of my dm-snapshot
discard changes that were merged over the weekend.  In addition, Nikos
inquired about his dm-kcopyd subjob size default adjustment I had
requested some changes on.  I've since dealt with those 2 issues and
staged 2 other small fixes (to dm-zoned and DM core's printk wrappers).

The following changes since commit bd293d071ffe65e645b4d8104f9d8fe15ea13862:

  dm bufio: fix deadlock with loop device (2019-07-12 09:59:37 -0400)

are available in the Git repository at:

  dm: use printk ratelimiting functions (2019-07-17 13:09:32 -0400)

Please pull, thanks!
Mike

----------------------------------------------------------------
- Fix zone state management race in DM zoned target by eliminating
  the unnecessary DMZ_ACTIVE state.

- A couple fixes for issues the DM snapshot target's optional discard
  support added during first week of the 5.3 merge.

- Increase default size of outstanding IO that is allowed for a each
  dm-kcopyd client and introduce tunable to allow user adjust.

- Update DM core to use printk ratelimiting functions rather than
  duplicate them and in doing so fix an issue where DMDEBUG_LIMIT() rate
  limited KERN_DEBUG messages had excessive "callbacks suppressed"
  messages.
