Subject: [PATCH bpf-next v4 1/7] bpf: Make struct cgroup btf id global
Date: Sun, 23 Oct 2022 11:05:19 -0700	[thread overview]
Message-ID: <20221023180519.2858371-1-yhs@fb.com> (raw)
In-Reply-To: <20221023180514.2857498-1-yhs@fb.com>

Make struct cgroup btf id global so later patch can reuse
the same btf id.
