  Modified files:
    sys/fs/fifofs        fifo_vnops.c 
  Log:
  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).
