Re: [PATCH iproute2-next 1/3] libbpf: Use bpf_object__load instead of bpf_object__load_xattr

[Hangbin Liu <haliu@redhat.com>]

Hi David,

This patch revert c04e45d0 lib/bpf: fix verbose flag when using libbpf,
Should we set prog->log_level directly before it loaded, like
bpf_program__set_log_level() does?

Thanks
Hangbin
