Merge branch 'bpftool: improve split BTF support'
Andrii Nakryiko says:
====================
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.
