sys/kern kern_event.c
Log:
Kqueue_scan() may sleep when encountered the influx knotes. On the other
hand, it may cause other threads to sleep since kqueue_scan() may mark
some knotes as infux. This could lead to the deadlock.
Before kqueue_scan() sleeps, wakeup the threads that are waiting for the
influx knotes produced by this thread.
