# Merge: 6860c981b967 733232f8c852
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     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
