  Modified files:
    sys/kern             kern_exit.c kern_ktrace.c kern_shutdown.c 
                         subr_taskqueue.c 
  Log:
  If we fail to write to a vnode during a ktrace write, then we drop all
  other references to that vnode as a trace vnode in other processes as well
  as in any pending requests on the todo list.  Thus, it is possible for a
  ktrace request structure to have a NULL ktr_vp when it is destroyed in
  ktr_freerequest().  We shouldn't call vrele() on the vnode in that case.
