Modified files:
sys/kern kern_proc.c subr_witness.c
sys/sys proc.h
Log:
- Merge the pgrpsess_lock and proctree_lock sx locks into one proctree_lock
sx lock. Trying to get the lock order between these locks was getting
too complicated as the locking in wait1() was being fixed.
- leavepgrp() now requires an exclusive lock of proctree_lock to be held
when it is called.
- fixjobc() no longer gets a shared lock of proctree_lock now that it
requires an xlock be held by the caller.
- Locking notes in sys/proc.h are adjusted to note that everything that
used to be protected by the pgrpsess_lock is now protected by the
proctree_lock.
