Hi all,

After merging the bpf-next tree, today's linux-next build (powerpcle perf)
failed like this:

util/bpf-loader.c: In function 'config_bpf_program':
util/bpf-loader.c:331:2: error: 'bpf_program__title' is deprecated: BPF program title is confusing term; please use bpf_program__section_name() instead [-Werror=deprecated-declarations]
  331 |  config_str = bpf_program__title(prog, false);
      |  ^~~~~~~~~~

Caused or exposed by commit

  521095842027 ("libbpf: Deprecate notion of BPF program "title" in favor of "section name"")

I have used the bpf-next tree from next-20200903 for today.
