sys/kern : kern_lock.c
Log message:
Fix memory barrier in __mtx_leave(). membar_exit_before_atomic() cannot
be used in the routine because there is no subsequent atomic operation.
membar_exit() has to be used instead.
The mistake has not caused problems because on most platforms
membar_exit_before_atomic() is membar_exit(). Only amd64 and i386 have
a dedicated membar_exit_before_atomic(), and their exit barriers are
no-ops.
