Subject: [PATCH bpf-next v3 04/12] bpf: tcp: guard declarations with CONFIG_NET_SOCK_MSG
Date: Wed, 4 Mar 2020 11:13:09 +0100 [thread overview]
Message-ID: <20200304101318.5225-5-lmb@cloudflare.com> (raw)
In-Reply-To: <20200304101318.5225-1-lmb@cloudflare.com>
tcp_bpf.c is only included in the build if CONFIG_NET_SOCK_MSG is
selected. The declaration should therefore be guarded as such.
