Subject: [PATCH bpf-next 0/3] bpftool: improve split BTF support

Few follow up improvements to bpftool for split BTF support:
  - emit "name <anon>" for non-named BTFs in `bpftool btf show` command;
  - when dumping /sys/kernel/btf/<module> use /sys/kernel/btf/vmlinux as the
    base BTF, unless base BTF is explicitly specified with -B flag.

This patch set also adds btf__base_btf() getter to access base BTF of the
struct btf.

Andrii Nakryiko (3):
  tools/bpftool: emit name <anon> for anonymous BTFs
  libbpf: add base BTF accessor
  tools/bpftool: auto-detect split BTFs in common cases
