Subject: [PATCH bpf-next 01/21] bpf: Add base proto function for cgroup-bpf programs
Date: Sat, 23 Mar 2019 17:12:14 -0700	[thread overview]
Message-ID: <fec8fdc6c6cc41caa66cb998453184b1c4b1f911.1553385598.git.rdna@fb.com> (raw)
In-Reply-To: <cover.1553385598.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().
