Subject: [RFC net-next 0/2] Introduce bpf_prog ID and iteration

This patchset introduces the bpf_prog ID and a new bpf cmd to
iterate all bpf_prog in the system.

It is still incomplete.  The idea can be extended to bpf_map.

Martin KaFai Lau (2):
  bpf: Introduce bpf_prog ID
  bpf: Test for bpf_prog ID and BPF_PROG_GET_NEXT_ID
