Subject: [PATCH bpf-next v2 01/35] bpf: memcg-based memory accounting for bpf progs
Date: Mon, 27 Jul 2020 11:44:32 -0700 [thread overview]
Message-ID: <20200727184506.2279656-2-guro@fb.com> (raw)
In-Reply-To: <20200727184506.2279656-1-guro@fb.com>
Include memory used by bpf programs into the memcg-based accounting.
This includes the memory used by programs itself, auxiliary data
and statistics.
