Potential confusion lurking here. IIRC the intended purpose of SCSI-2 
RESERVE/RELEASE is to avoid contention in multi-initiator 
configurations, e.g. SANs and clustering, where the same device can be 
used by multiple hosts. I think your description will be confusing for 
those been using this SCSI terminology for 20 years. Perhaps some 
additional clarification or different command names should be used.
