  Modified files:        (Branch: RELENG_4)
    sys/dev/vn           vn.c 
  Log:
  Clean up properly when a `vn' module is kldunloaded to avoid panics
  later. We now call cdesw_remove() to unregister the device, NULL
  out any pointers to the vn_softc that exist in dev_t `si_drv1'
  fields, and perform a destroy_dev() corresponding to the initial
  make_dev().
  
  This is not an MFC; vn(4) is no longer in -current.
