sys/kern : kern_synch.c
Log message:
Ensure that timeout p_sleep_to is not left running when finishing sleep.
This is necessary when invoking sleep_finish_timeout() without the
kernel lock. If not cancelled properly, an already running endtsleep()
might cause a spurious wakeup on the thread if the thread re-enters
a sleep queue very quickly before the handler completes.
The flag P_TIMEOUT should stay cleared across the timeout cancellation.
Add an assertion for that.
