     81         * should probably free pathloc in either case:
     82         *  - if the link evaluation fails, it must free the
     83         *    original (valid) pathloc because we are going
     84         *    to return -1 and hence the FS generics won't
     85         *    cleanup pathloc.
     86         *  - if the link evaluation is successful, the updated
     87         *    pathloc will be passed up (and eventually released).
     88         *    Hence, the (valid) originial node that we submit to
     89         *    eval_link_h() should be released by the handler.
