Subject: [PATCH bpf-next] bpf/btf: Use btf_type_str() whenever possible
Date: Tue, 13 Sep 2022 19:13:28 -0700 [thread overview]
Message-ID: <20220914021328.17039-1-yepeilin.cs@gmail.com> (raw)
From: Peilin Ye <peilin.ye@bytedance.com>
We have btf_type_str(). Use it whenever possible in btf.c, instead of
"btf_kind_str[BTF_INFO_KIND(t->info)]".
