Subject: [PATCH bpf-next 0/4] bpftool: Add struct_ops support

This set adds "struct_ops" support to bpftool.

The first two patches improve the btf_dumper in bpftool.
Patch 1: print the enum's name (if it is found) instead of the
         enum's value.
Patch 2: print a char[] as a string if all characters are printable.

"struct_ops" stores the prog_id in a func ptr.
Instead of printing a prog_id,
patch 3 adds an option to btf_dumper to allow a func ptr's value
to be printed with the full func_proto info and the prog_name.

Patch 4 implements the "struct_ops" bpftool command.

Martin KaFai Lau (4):
  bpftool: Print the enum's name instead of value
  bpftool: Print as a string for char array
  bpftool: Translate prog_id to its bpf prog_name
  bpftool: Add struct_ops support
