sys/kern : kern_exit.c kern_fork.c kern_resource.c
kern_sig.c kern_synch.c
sys/sys : proc.h
Log message:
Change how ps_threads and p_thr_link are locked away from using SCHED_LOCK.
The per process thread list can be traversed (read) by holding either
the KERNEL_LOCK or the per process ps_mtx (instead of SCHED_LOCK).
Abusing the SCHED_LOCK for this makes it impossible to split up the
scheduler lock into something more fine grained.
