Subject: [PATCH bpf-next v9 11/34] bpf: refine memcg-based memory accounting for devmap maps
Date: Tue, 1 Dec 2020 13:58:37 -0800	[thread overview]
Message-ID: <20201201215900.3569844-12-guro@fb.com> (raw)
In-Reply-To: <20201201215900.3569844-1-guro@fb.com>

Include map metadata and the node size (struct bpf_dtab_netdev)
into the accounting.
