Subject: [PATCH] mm/memcg: update obsolete comment above parent_mem_cgroup()
Date: Tue, 1 Aug 2023 20:43:59 +0800 [thread overview]
Message-ID: <20230801124359.2266860-1-linmiaohe@huawei.com> (raw)
Since commit bef8620cd8e0 ("mm: memcg: deprecate the non-hierarchical
mode"), use_hierarchy is already deprecated. And it's further removed
via commit 9d9d341df4d5 ("cgroup: remove obsoleted broken_hierarchy
and warned_broken_hierarchy"). Update corresponding comment.
