Subject: [PATCH v3 bpf-next 01/21] bpf: Add base proto function for cgroup-bpf programs
Date: Fri, 5 Apr 2019 12:35:23 -0700 [thread overview]
Message-ID: <caa3d6730845e22ab5fe70fb9da8e467b2d024db.1554485409.git.rdna@fb.com> (raw)
In-Reply-To: <cover.1554485409.git.rdna@fb.com>
Currently kernel/bpf/cgroup.c contains only one program type and one
proto function cgroup_dev_func_proto(). It'd be useful to have base
proto function that can be reused for new cgroup-bpf program types
coming soon.
Introduce cgroup_base_func_proto().
