Subject: [PATCH v5 09/16] memcg: enable accounting for file lock caches
Date: Mon, 19 Jul 2021 13:45:15 +0300 [thread overview]
Message-ID: <c19db2e9-b020-f83f-7627-fcc31aac9108@virtuozzo.com> (raw)
In-Reply-To: <cover.1626688654.git.vvs@virtuozzo.com>
User can create file locks for each open file and force kernel
to allocate small but long-living objects per each open file.
It makes sense to account for these objects to limit the host's memory
consumption from inside the memcg-limited container.
