From e14ef4bf011192b61b48c4f3a35b3041140073ff Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Thu, 18 Mar 2021 12:40:25 -0700 Subject: [PATCH] libbpf: Expose btf_type_by_id() internally 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.
