sys/netinet ip_mroute.c
Log:
Potential fix for races shutting down callouts when unloading
the module. Previously we grabbed the mutex used by the callouts,
then stopped the callout with callout_stop, but if the callout
was already active and blocked by the mutex then it would continue
later and reference the mutex after it was destroyed. Instead
stop the callout first then lock.
