Subject: [PATCH bpf-next 11/35] bpf: refine memcg-based memory accounting for sockmap maps
Date: Fri, 24 Jul 2020 17:03:46 -0700	[thread overview]
Message-ID: <20200725000410.3566700-12-guro@fb.com> (raw)
In-Reply-To: <20200725000410.3566700-1-guro@fb.com>

Include sockmap internal metadata into the memcg-based memory
accounting. Also include the memory allocated on updating an element.
