Besides the OSD command set that never got traction, the only SCSI

sense to keep the support code around just for that, so start
deprecating the support.

You are the bsg maintainer, so I expected you to pick it up :)
OK - did you to amend the commit message to reflect the death of
XDWRITEREAD as well?
It was made obsolete in _draft_ sbc4r15.pdf according to my notes.
It is not "dead", not until SBC-4 is ratified. Until then, SBC-3 is the
current SCSI "block" device standard and it is there as a non-mandatory
command.
