Merge tag 'for-6.9/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

Pull device mapper updates from Mike Snitzer:

 - Fix DM core's IO submission (which include dm-io and dm-bufio) such
   that a bio's IO priority is propagated. Work focused on enabling both
   DM crypt and verity targets to retain the appropriate IO priority

 - Fix DM raid reshape logic to not allow an empty flush bio to be
   requeued due to false concern about the bio, which doesn't have a
   data payload, accessing beyond the end of the device

 - Fix DM core's internal resume so that it properly calls both presume
   and resume methods, which fixes the potential for a postsuspend and
   resume imbalance

 - Update DM verity target to set DM_TARGET_SINGLETON flag because it
   doesn't make sense to have a DM table with a mix of targets that
   include dm-verity

 - Small cleanups in DM crypt, thin, and integrity targets

 - Fix references to dm-devel mailing list to use latest list address
