Subject: [PATCH v6 1/2] mm: memcontrol: Fix missing suffix of workingset_restore
Date: Wed, 16 Sep 2020 18:00:29 +0800	[thread overview]
Message-ID: <20200916100030.71698-1-songmuchun@bytedance.com> (raw)

We forget to add the suffix to the workingset_restore string, so
fix it. And also update the documentation of cgroup-v2.rst.

Fixes: 170b04b7ae49 ("mm/workingset: prepare the workingset detection infrastructure for anon LRU")
Signed-off-by: Muchun Song <songmuchun@bytedance.com>

 changelog in v6:
 1. There is no version of v1-v5.
