I think I had two things in mind here:
- I don't know of any drivers that actually return any errors ever from
req_notify_cq so it's not really a practical concern.
- If we did get an error, there's not much we can do except keep
polling and try to request notification again later -- exactly the
same thing we would do if we got a positive return value.
