Subject: [PATCH RFC 0/3] bpf: show attached name for progs without btf name

With progs.debug we can get the attached name of the bpf prog which is
attached to a kernel function. But we can't get bpf progs which are
attached to others, like a cgroup, sockmap and etc. This patchset means
to extend the attached name to other types.

The member attach_func_name in struct bpf_prog_aux is renamed to
attach_name in patch #1, to avoid possible confusion. Then in patch #2
and #3 I extend the attached name to bpf progs which are attached to a
cgroup or a sockmap. If this solution is acceptable, I will extend it to
other attach types in the next step.

Yafang Shao (3):
  bpf: rename attach_func_name to attach_name
  bpf: set attached cgroup name in attach_name
  bpf: set attached sockmap id in attach_name
