This isn't really true. If you implement them as different LUNs on the
same unit, the SCSI layer won't allow them to both have a command active
at once.
Besides, the control thread for the unit will serialize the commands.
OK.
Still, such solutions (have a struct with two pointers and two
destructor routines in us->extra; have the driver copy this to
some local variables and replace us->extra when it calls the
subdriver to do the work, and restore things again when the
subdriver is done) feel extremely fragile and kludgy.
You are not really suggesting the above?
