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

Pull SCSI updates from James Bottomley:
 "Usual driver updates (ufs, lpfc, target, qla2xxx) plus assorted
  cleanups and fixes including the WQ_PERCPU series.

  The biggest core change is the new allocation of pseudo-devices which
  allow the sending of internal commands to a given SCSI target"
