Subject: Re: [PATCH bpf-next 01/10] bpf: btf: Introduce BPF Type Format (BTF)

Hi Martin,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on bpf-next/master]

url:    https://github.com/0day-ci/linux/commits/Martin-KaFai-Lau/BTF-BPF-Type-Format/20180331-144656
base:   https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git master
reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF=-D__CHECK_ENDIAN__


sparse warnings: (new ones prefixed by >>)

>> kernel/bpf/btf.c:666:28: sparse: symbol 'enum_ops' was not declared. Should it be static?
   kernel/bpf/btf.c:833:20: warning: 'btf_parse' defined but not used [-Wunused-function]
    static struct btf *btf_parse(void __user *btf_data, u32 btf_data_size,
                       ^~~~~~~~~

Please review and possibly fold the followup patch.
