Subject: mm/memcg: update obsolete comment above parent_mem_cgroup()
Date: Tue, 1 Aug 2023 20:43:59 +0800

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.
