Modified files:
sys/kern kern_kthread.c
Log:
- Use _PHOLD and move it before a PROC_UNLOCK to reduce the number of
mutex operations in kthread_create().
- Lock a kthread's proc before changing its parent via proc_reparent().
- Test P_KTHREAD not P_SYSTEM in kthread_suspend() and kthread_resume().
P_SYSTEM just means that the process shouldn't be swapped and is used
for vinum's daemon for example.
- Lock all the signal state used for suspending and resuming kthreads with
the proc lock.
