Per spec:
"Additionally, exporting a fence payload to a handle with copy transference has
the same side effects
on the source fence’s payload as executing a fence reset operation. If the
fence was using a
temporarily imported payload, the fence’s prior permanent payload will be
restored."
And similar for semaphores:
"Additionally, exporting a semaphore payload to a handle with copy transference
has the same side
effects on the source semaphore’s payload as executing a semaphore wait
operation. If the
semaphore was using a temporarily imported payload, the semaphore’s prior
permanent payload
will be restored."
Fixes: 42bc25a79c "radv: Advertise sync fd import and export."
