Regarding "Exclusive Access, Registrants Only", my recollection is that
both read and write access are limited to those initiators that have
registered with the device server.  Your phrasing above is unclear, and
seems to discuss only write access.

Beware that I don't have my copy of the Persistent Reservations spec in
front of me, so please look at your copy and don't just believe me.
