    The first argument that is passed to sysfs show and store methods is
    a kobject pointer. Have you considered to access kobject.parent from
    inside the show/store methods? From fs/sysfs/file.c:

    if (ops->show) {
    count = ops->show(kobj, of->kn->priv, buf);
    if (count < 0)
    return count;
    }
