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

Pull final round of SCSI updates from James Bottomley:
 "This is the remaining set of SCSI patches for the merge window.  It's
  mostly driver updates (scsi_debug, qla2xxx, storvsc, mp3sas).  There
  are also several bug fixes in fcoe, libfc, and megaraid_sas.  We also
  have a couple of core changes to try to make device destruction more
  deterministic"
