Subject: [PATCH bpf-next 02/11] btf: add a global set of valid BTF socket ids
Date: Fri, 4 Sep 2020 12:23:52 +0100 [thread overview]
Message-ID: <20200904112401.667645-3-lmb@cloudflare.com> (raw)
In-Reply-To: <20200904112401.667645-1-lmb@cloudflare.com>
Similar to the existing btf_sock_ids, add a set for the same data.
This allows searching for sockets using btf_set_contains.
