Pull SCSI fixes from James Bottomley:
 "Three small bug fixes (barrier elimination, memory leak on unload,
  spinlock recursion) and a technical enhancement left over from the
  merge window: the TCMU read length support is required for tape
  devices read when the length of the read is greater than the tape
  block size"
