# commit 2a89b99f580371b86ae9bafd6cbeccd3bfab524a
# Merge: ce69fb3b392f 6958c1c640af
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Thu Jul 9 13:14:51 2020 -0700
# 
#     Merge tag 'for-5.8/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
#     
#     Pull device mapper fixes from Mike Snitzer:
#     
#      - A request-based DM fix to not use a waitqueue to wait for blk-mq IO
#        completion because doing so is racey.
#     
#      - A couple more DM zoned target fixes to address issues introduced
#        during the 5.8 cycle.
#     
#      - A DM core fix to use proper interface to cleanup DM's static flush
#        bio.
#     
#      - A DM core fix to prevent mm recursion during memory allocation needed
#        by dm_kobject_uevent.
#     
#     * tag 'for-5.8/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
#       dm: use noio when sending kobject event
#       dm zoned: Fix zone reclaim trigger
#       dm zoned: fix unused but set variable warnings
#       dm writecache: reject asynchronous pmem devices
#       dm: use bio_uninit instead of bio_disassociate_blkg
#       dm: do not use waitqueue for request-based DM
