Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull SCSI updates from James Bottomley:
 "This is mostly update of the usual drivers: qla2xxx, ufs, smartpqi,
  lpfc, hisi_sas, qedf, mpt3sas; plus a whole load of minor updates. The
  only core change this time around is the addition of request batching
  for virtio. Since batching requires an additional flag to use, it
  should be invisible to the rest of the drivers"
