sys/kern subr_turnstile.c
Log:
Always explicitly panic in propogate_priority() if we try to propogate
a lock's priority to a sleeping thread. When we panic, dump a stack
trace of the thread that is asleep if DDB is compiled into the kernel
just before calling panic(). This is much more informative and useful
for debugging than the current behavior of getting a page fault and not
having an easy way of determining which thread caused the original problem.
