Merge tag 'dm-4.5-fix' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper...

Pull device mapper fix from Mike Snitzer:
 "Fix a 112 byte leak for each IO request that is requeued while DM
  multipath is handling faults due to path failures.

  This leak does not happen if blk-mq DM multipath is used.  It only
  occurs if .request_fn DM multipath is stacked ontop of blk-mq paths
  (e.g. scsi-mq devices)"
