[Iscsitarget-devel] SCSI-3 Persistent Reservations: support for all-registrants types?

[Lee Duncan]

Hello:

I have been looking at the iscsitarget sources, and it looks like the
SCSI-3 Persistent Reservation support does not support registration
types 7 and 8, which are the "write exclusive, all registrants" and
"exclusive access, all registrants" types.

Are there any current plans to add support for these types? Evidently,
IBMs GPFS uses type=7.

If there are no current plans, would you be open to me submitting a
patch for this?
