Subject: [PATCH bpf-next v3 05/29] bpf: memcg-based memory accounting for cgroup storage maps
Date: Thu, 30 Jul 2020 14:22:46 -0700	[thread overview]
Message-ID: <20200730212310.2609108-6-guro@fb.com> (raw)
In-Reply-To: <20200730212310.2609108-1-guro@fb.com>

Account memory used by cgroup storage maps including the percpu memory
for the percpu flavor of cgroup storage and map metadata.
