Subject: [PATCH 13/17] mm: workingset: allocate list_lru on xa_node allocation
Date: Tue, 11 May 2021 18:46:43 +0800	[thread overview]
Message-ID: <20210511104647.604-14-songmuchun@bytedance.com> (raw)
In-Reply-To: <20210511104647.604-1-songmuchun@bytedance.com>

The workingset will add the xa_node to its list_lru, we should use
xas_set_lru() to pass which lru we want to insert.
