- 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.
