Subject: [patch 04/19] mm: memcg: fix memcg file_dirty numa stat
Date: Sat, 23 Jan 2021 21:01:11 -0800	[thread overview]
Message-ID: <20210124050111.gKSNEIDmu%akpm@linux-foundation.org> (raw)
In-Reply-To: <20210123210029.a7c704d0cab204683e41ad10@linux-foundation.org>

Subject: mm: memcg: fix memcg file_dirty numa stat

The kernel updates the per-node NR_FILE_DIRTY stats on page migration but
not the memcg numa stats.  That was not an issue until recently the commit
5f9a4f4a7096 ("mm: memcontrol: add the missing numa_stat interface for
cgroup v2") exposed numa stats for the memcg.  So fix the file_dirty
per-memcg numa stat.
