Subject: [PATCH bpf-next v2 1/6] bpf: Make struct cgroup btf id global
Date: Thu, 20 Oct 2022 15:13:01 -0700 [thread overview]
Message-ID: <20221020221301.3554017-1-yhs@fb.com> (raw)
In-Reply-To: <20221020221255.3553649-1-yhs@fb.com>
Make struct cgroup btf id global so later patch can reuse
the same btf id.
