Subject: [PATCH v3 75/76] mm: list_lru: rename list_lru_per_memcg to list_lru_memcg
Date: Tue, 14 Sep 2021 15:29:37 +0800	[thread overview]
Message-ID: <20210914072938.6440-76-songmuchun@bytedance.com> (raw)
In-Reply-To: <20210914072938.6440-1-songmuchun@bytedance.com>

Before now, the name of list_lru_memcg was occupied. Since previous
patch, the name is free. So rename list_lru_per_memcg to list_lru_memcg,
it is more brief.
