I believe not the abstract (empty) task should be invoked, but a real task which does the work. Presumably if we want to schedule a way networking part to copy its counters, system should wake up the appropriate userspace thread blocked in a grace-period waking path, so effectively either RCU callback processing code or some registered thread should be awakened.
Just a detail though.
