Agreed...   DEF_SCSI_QCMD was intended, as you note, to encourage a 
piecemeal, in-depth approach to cleaning up the rest of the drivers. 
Hopefully DEF_SCSI_QCMD removal means someone actually figured out [or 
already knew] the locking for a driver, and created the most appropriate 
patch, rather than another half-step.
