named ``0`` to ``N-1``. Each directory represents each filter and works in a
way similar to that for :ref:`DAMOS filter <sysfs_filters>`. When the filter
``type`` is ``memcg``, ``path`` file acts as ``memcg_path`` for :ref:`DAMOS
filter <sysfs_filters>`. When the filter ``type`` is ``hugepage_size``,
``min`` and ``max`` files act as files of the same names for :ref:`DAMOS
filter <sysfs_filters>`.
