Subject: [PATCH bpf-next v4 02/30] bpf: memcg-based memory accounting for bpf progs
Date: Fri, 21 Aug 2020 08:01:06 -0700 [thread overview]
Message-ID: <20200821150134.2581465-3-guro@fb.com> (raw)
In-Reply-To: <20200821150134.2581465-1-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.
