Hi David,
if you want to add SCSI-2 RESERVE/RELEASE it would be at least
different opcodes if not an entirely different API. But what for?
RESERVE/RELEASE are basially unsuable and that's why there are
almost no users out there, and they can usually prefer SCSI-3
semantics.
If you have a real users feel free to propose patches and I'm happy to
review them.
