Merge tag 'for-4.15/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:
 "Given your expected travel I figured I'd get these fixes to you sooner
  rather than later.

   - a DM multipath stable@ fix to silence an annoying error message
     that isn't _really_ an error

   - a DM core @stable fix for discard support that was enabled for an
     entire DM device despite only having partial support for discards
     due to a mix of discard capabilities across the underlying devices.

   - a couple other DM core discard fixes.

   - a DM bufio @stable fix that resolves a 32-bit overflow"

* tag 'for-4.15/dm-changes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
  dm bufio: fix integer overflow when limiting maximum cache size
  dm: clear all discard attributes in queue_limits when discards are disabled
  dm: do not set 'discards_supported' in targets that do not need it
  dm: discard support requires all targets in a table support discards
  dm mpath: remove annoying message of 'blk_get_request() returned -11'
