bpf: Make function btf_name_offset_valid static
Initially in commit 69b693f0aefa ("bpf: btf: Introduce BPF Type Format (BTF)") the function 'btf_name_offset_valid' was introduced as static function it was later on changed to a non-static one, and then finally in commit 23127b33ec80 ("bpf: Create a new btf_name_by_offset() for non type name use case") the function prototype was removed. Revert back to original implementation and make the function static. Remove warning triggered with W=1: kernel/bpf/btf.c:470:6: warning: no previous prototype for 'btf_name_offset_valid' [-Wmissing-prototypes] Fixes: 23127b33ec80 ("bpf: Create a new btf_name_by_offset() for non type name use case") Signed-off-by: Mathieu Malaterre <malat@debian.org> Acked-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
