Merge tag 'for-5.3/dm-changes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull more device mapper updates from Mike Snitzer: - 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. * tag 'for-5.3/dm-changes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm: use printk ratelimiting functions dm kcopyd: Increase default sub-job size to 512KB dm snapshot: fix oversights in optional discard support dm zoned: fix zone state management race
