  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.
