Subject: [patch 055/200] mm: memcontrol: add file_thp, shmem_thp to memory.stat
Date: Mon, 14 Dec 2020 19:06:20 -0800	[thread overview]
Message-ID: <20201215030620.kwmNIBasi%akpm@linux-foundation.org> (raw)
In-Reply-To: <20201214190237.a17b70ae14f129e2dca3d204@linux-foundation.org>

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: memcontrol: add file_thp, shmem_thp to memory.stat

As huge page usage in the page cache and for shmem files proliferates in
our production environment, the performance monitoring team has asked for
per-cgroup stats on those pages.

We already track and export anon_thp per cgroup.  We already track file
THP and shmem THP per node, so making them per-cgroup is only a matter of
switching from node to lruvec counters.  All callsites are in places where
the pages are charged and locked, so page->memcg is stable.

[hannes@cmpxchg.org: add documentation]
