As far as I can tell from reading the Verbs spec the raison d'êtrefor
protection domains is to allow associating MRs with different address
spaces in userspace programs.
Is there any good reason to have each kernel driver create it's own PDs
instead of simply creating one per device and sticking it into the
ib_device structure?
