Subject: [PATCH v4 bpf-next 01/12] libbpf: expose btf_type_by_id() internally
Date: Thu, 18 Mar 2021 12:40:25 -0700 [thread overview]
Message-ID: <20210318194036.3521577-2-andrii@kernel.org> (raw)
In-Reply-To: <20210318194036.3521577-1-andrii@kernel.org>
btf_type_by_id() is internal-only convenience API returning non-const pointer
to struct btf_type. Expose it outside of btf.c for re-use.
