Silly question perhaps:
Could we not have returned an existing (signalled) fence with
the wanted timestamp (when count == 0), as opposed to allocating a stub? Maybe
allocation should be avoided?
No a silly, but a very good question.
Answer is yes, that's what we have done previously. Problem with that
approach is that each fence reference prevents the driver who originally
issued this fence from being able to unload.
That's especially ugly in cases of hotplug because you have to keep a
zombie driver instance around for potentially quite some time.
