Modified files:
sys/kern kern_sig.c
Log:
- Move the second stop() of process 'p' in issignal() to be after we send
SIGCHLD to our parent process. Otherwise, we could block while obtaining
the process lock for our parent process and switch out while we were
in SSTOP. Even worse, when we try to resume from the mutex being blocked
on our p_stat will be SRUN, not SSTOP.
- Fix a comment above stop() to indicate that it requires that the proc lock
be held, not a proctree lock.
