When a map is storing a kernel's struct, its
map_info->btf_vmlinux_value_type_id is set.  The first map type
supporting it is BPF_MAP_TYPE_STRUCT_OPS.

This series adds support to dump this kind of map with BTF.
The first two patches are bug fixes which only applicable to
in bpf-next.

Please see individual patches for details.

Martin KaFai Lau (5):
  bpftool: Fix a leak of btf object
  bpftool: Fix missing BTF output for json during map dump
  libbpf: Expose bpf_find_kernel_btf to libbpf_internal.h
  bpftool: Add struct_ops map name
  bpftool: Support dumping a map with btf_vmlinux_value_type_id
