Subject: [Patch bpf-next v5 6/8] sock_map: make sock_map_prog_update() static
Date: Fri, 19 Feb 2021 15:58:34 -0800 [thread overview]
Message-ID: <20210219235836.100416-7-xiyou.wangcong@gmail.com> (raw)
In-Reply-To: <20210219235836.100416-1-xiyou.wangcong@gmail.com>
From: Cong Wang <cong.wang@bytedance.com>
It is only used within sock_map.c so can become static.
