The two patches I sent were supposed to be alternative solutions; see
https://marc.info/?l=linux-scsi&m=152063671005295&w=2 for the introduction (I
seem to have messed up the headers, so the mails didn’t end up threaded
properly).
The MAX_COMMAND_SIZE approach is nice and simple, but I thought it worth
eliminating scsi_command_size_tbl while I was at it...
Regards,
Stephen
