Modified files:
sys/kern kern_sig.c
Log:
The previous commit wasn't entirely correct. At least one goto to the
out: label in psignal() did not grab sched_lock before trying to release
it. Also, the previous version had several cases where it grabbed
sched_lock before jumping to out: unneccessarily, so rework this a bit.
The runfast: and out: labels must be called with sched_lock released, and
the run: label must be called with it held. Appropriate mtx_assert()'s
have been added that should catch any bugs that may still be in this
code.
