    sys/cam/scsi         scsi_target.c 
  Log:
  Make physical buffers in cam_periph_mapmem owned by the kernel in case we
  return to user space w/o waiting for I/O to complete.
  
  I tried to get several folks who know this code better than me to review it
  with no luck. I *do* know that w/o this code, using the SCSI target driver
  panics in userret (if it doesn't panic in knote first).
