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

Pull SCSI updates from James Bottomley:
 "This is an assorted set of stragglers into the merge window with
  driver updates for qla2xxx, megaraid_sas, storvsc and ufs.

  It also includes pulls of the uapi tree (all the remaining SCSI
  pieces) and the fcoe tree (updates to fcoe and libfc)"
