Subject: [patch 093/131] mm: memcontrol: switch to native NR_ANON_MAPPED counter
Date: Wed, 03 Jun 2020 16:01:57 -0700 [thread overview]
Message-ID: <20200603230157.d3kWqwSon%akpm@linux-foundation.org> (raw)
In-Reply-To: <20200603155549.e041363450869eaae4c7f05b@linux-foundation.org>
From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: memcontrol: switch to native NR_ANON_MAPPED counter
Memcg maintains a private MEMCG_RSS counter. This divergence from the
generic VM accounting means unnecessary code overhead, and creates a
dependency for memcg that page->mapping is set up at the time of charging,
so that page types can be told apart.
Convert the generic accounting sites to mod_lruvec_page_state and friends
to maintain the per-cgroup vmstat counter of NR_ANON_MAPPED. We use
lock_page_memcg() to stabilize page->mem_cgroup during rmap changes, the
same way we do for NR_FILE_MAPPED.
With the previous patch removing MEMCG_CACHE and the private NR_SHMEM
counter, this patch finally eliminates the need to have page->mapping set
up at charge time. However, we need to have page->mem_cgroup set up by
the time rmap runs and does the accounting, so switch the commit and the
rmap callbacks around.
v2: fix temporary accounting bug by switching rmap<->commit (Joonsoo)
