Subject: [PATCH v2 bpf-next 01/11] libbpf: expose btf_type_by_id() internally
Date: Sat, 13 Mar 2021 11:35:27 -0800	[thread overview]
Message-ID: <20210313193537.1548766-2-andrii@kernel.org> (raw)
In-Reply-To: <20210313193537.1548766-1-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.
