Hey SCSI experts,
Am I right to assume that /all/ SBC commands (I'm interested in READ
CAPACITY) should return CONFLICT to an unregistered I_T nexus when the
device server has Persistent Reservation, Exclusive Access - Registrants
Only?
I have access to SPC-4; table 66 only talks about SPC commands.
If so, I think it might make sense to call sd_revalidate_disk() directly
after a successful pr_register.

I found that SBC-4 specifies that READ CAPACITY should be allowed for all
reservation types, so it seems my issue is with the LIO target driver.
