Modified files:
sys/kern kern_ktrace.c
Log:
In ktr_getrequest(), acquire ktrace_mtx earlier -- while the race
currently present is minor and offers no real semantic issues, it also
doesn't make sense since an earlier lockless check has already
occurred. Also hold the mutex longer, over a manipulation of
per-process ktrace state, which requires synchronization.
