Subject: [PATCH bpf-next v6 07/34] bpf: memcg-based memory accounting for bpf maps
Date: Mon, 16 Nov 2020 19:40:41 -0800 [thread overview]
Message-ID: <20201117034108.1186569-8-guro@fb.com> (raw)
In-Reply-To: <20201117034108.1186569-1-guro@fb.com>
This patch enables memcg-based memory accounting for memory allocated
by __bpf_map_area_alloc(), which is used by many types of bpf maps for
large memory allocations.
Following patches in the series will refine the accounting for
some of the map types.
