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

Pull SCSI updates from James Bottomley:
 "First round of SCSI updates for the 4.6+ merge window.

  This batch includes the usual quota of driver updates (bnx2fc, mp3sas,
  hpsa, ncr5380, lpfc, hisi_sas, snic, aacraid, megaraid_sas).  There's
  also a multiqueue update for scsi_debug, assorted bug fixes and a few
  other minor updates (refactor of scsi_sg_pools into generic code, alua
  and VPD updates, and struct timeval conversions)"
