En walk_down_proc también tenemos BUG_ON(refs == 0), lo que podría suceder si tenemos corrupción del árbol de extensión. Cambia eso para que devuelva -EUCLEAN. En do_walk_down() capturamos este caso y lo manejamos correctamente, sin embargo, devolvemos -EIO, que -EUCLEAN es un código de error más apropiado.
