By the way, should we add a tracepoint likes trace_napi_poll() to make
it easier? Something likes:
        if (unlikely(budget <= 0 ||
                 time_after_eq(jiffies, time_limit))) {
            sd->time_squeeze++;
+            trace_napi_poll(budget, jiffies, time_limit);
            break;
        }
