Note that when the UA_INTLCK_CTRL field of the control mode page is set to
10b or 11b, REQUEST SENSE is the only way to clear a unit attention
condition. Choose one of:
1. Keep REQUEST SENSE mandatory for all devices and device types.
2. Complex wording saying that REQUEST SENSE is only mandatory for LUs
that allow UA_INTLCK_CTRL to be set to 10b or 11b.
3. Saying nothing and leaving the inference as an exercise for the
implementor.
I think everyone's life would be simpler if we kept REQUEST SENSE mandatory
for all device types, but I do have some sympathy for each position.
