    sys/fs/fifofs        fifo_vnops.c 
  Merge fifo_vnops.c:1.122 from HEAD to RELENG_6:
    Annotate two issues:
    1) fifo_kqfilter() is not actually ever used, it likely should be GC'd.
    2) fifo_kqfilter_f() doesn't implement EVFILT_VNODE, so detecting events
       on the underlying vnode for a fifo no longer works (it did in 4.x).
       Likely, fifo_kqfilter_f() should forward the request to the VFS using
       fp->f_vnode, which would work once fifo_kqfilter() was detached from
       the vnode operation vector (removing the fifo override).
