SCSI updates from James Bottomley:
 "The update includes the usual assortment of driver updates (lpfc,
  qla2xxx, qla4xxx, bfa, bnx2fc, bnx2i, isci, fcoe, hpsa) plus a huge
  amount of infrastructure work in the SAS library and transport class
  as well as an iSCSI update.  There's also a new SCSI based virtio
  driver."
