Modified files:
sys/kern kern_fork.c
Log:
- Lock the forklist with an sx lock.
- Add proc locking to fork1(). Always lock the child procoess (new
process) first when both processes need to be locked at the same
time.
- Remove unneeded spl()'s as the data they protected is now locked.
- Ensure that the proctree is exclusively locked and the new process is
locked when setting up the parent process pointer.
- Lock the check for P_KTHREAD in p_flag in fork_exit().
