From: luoliang The btf_vlen(), btf_kind() and btf_kflag() inline helpers defined in tools/lib/bpf/btf.h are thin wrappers around the BTF_INFO_VLEN(), BTF_INFO_KIND() and BTF_INFO_KFLAG() UAPI macros - each one simply returns the corresponding macro applied to t->info. bpftool already uses these helpers in most places, but 13 call sites in btf.c and btf_dumper.c still open-code the raw macros. Use the helpers consistently, matching the rest of bpftool as well as libbpf. No functional change.
