[PATCH bpf-next 0/2] selftests/bpf: BTF-based kernel data display fixes

Resolve issues in bpf selftests introduced with BTF-based kernel data
display selftests; these are

- a warning introduced in snprintf_btf.c; and
- compilation failures with old kernels vmlinux.h

Alan Maguire (2):
  selftests/bpf: fix unused-result warning in snprintf_btf.c
  selftests/bpf: ensure snprintf_btf/bpf_iter tests compatibility with
    old vmlinux.h
