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

Pull SCSI updates from James Bottomley:
 "This consists of the usual driver updates (ufs, target, tcmu,
  smartpqi, lpfc, zfcp, qla2xxx, mpt3sas, pm80xx).

  The major core change is using a sbitmap instead of an atomic for
  queue tracking"
