Pull more SCSI updates from James Bottomley:
 "The vfs has long had a write lifetime hint mechanism that gives the
  expected longevity on storage of the data being written. f2fs was the
  original consumer of this and used the hint for flash data placement
  (mostly to avoid write amplification by placing objects with similar
  lifetimes in the same erase block).

  More recently the SCSI based UFS (Universal Flash Storage) drivers
  have wanted to take advantage of this as well, for the same reasons as
  f2fs, necessitating plumbing the write hints through the block layer
  and then adding it to the SCSI core.

  The vfs write_hints already taken plumbs this as far as block and this
  completes the SCSI core enabling based on a recently agreed reuse of
  the old write command group number. The additions to the scsi_debug
  driver are for emulating this property so we can run tests on it in
  the absence of an actual UFS device"
