I think the EISDIR error is coming from kern/vfs_lookup.c, lookup()
function with cn_nameptr = "":


        /*
         * Check for degenerate name (e.g. / or "")
         * which is a way of talking about a directory,
         * e.g. like "/." or ".".
         */
        if (cnp->cn_nameptr[0] == '\0') {
                ...
                if (cnp->cn_nameiop != LOOKUP) {
                        error = EISDIR;
                        goto bad;
                }
                ...
