Suppose that an initiator registers using the ALL_TG_PT option.

Sometime later for whatever reason, the initiator decides to
preempt its own reservation key.

Would you expect that:

  a) the registration is preempted on all target ports except
     the target port through which the preempt was delivered, or
  b) the registration is not preempted on any of the target
     ports associated with the preempting initiator?

I believe that SPC-3 says a). Furthermore, the a) interpretation
is being solidified by seemingly editorial requests to change
'initiator port' to 'I_T nexus' throughout the Persistent
Reservations model.
