Subject: [PATCH bpf-next 01/35] bpf: memcg-based memory accounting for bpf progs
Date: Fri, 24 Jul 2020 17:03:36 -0700	[thread overview]
Message-ID: <20200725000410.3566700-2-guro@fb.com> (raw)
In-Reply-To: <20200725000410.3566700-1-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.
