Subject: [PATCH bpf-next v6 05/34] bpf: memcg-based memory accounting for bpf progs
Date: Mon, 16 Nov 2020 19:40:39 -0800 [thread overview]
Message-ID: <20201117034108.1186569-6-guro@fb.com> (raw)
In-Reply-To: <20201117034108.1186569-1-guro@fb.com>
Include memory used by bpf programs into the memcg-based accounting.
This includes the memory used by programs itself, auxiliary data,
statistics and bpf line info. A memory cgroup containing the
process which loads the program is getting charged.
