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.
