Subject: [PATCH net-next 0/8] Introduce bpf ID

This patch series:
1) Introduce ID for both bpf_prog and bpf_map.
2) Add bpf commands to iterate the prog IDs and map
   IDs of the system.
3) Add bpf commands to get a prog/map fd from an ID
4) Add bpf command to get prog/map info from a fd.
   The prog/map info is a jump start in this patchset
   and it is not meant to be a complete list.  They can
   be extended in the future patches.

Martin KaFai Lau (8):
  bpf: Introduce bpf_prog ID
  bpf: Introduce bpf_map ID
  bpf: Add BPF_(PROG|MAP)_GET_NEXT_ID command
  bpf: Add BPF_PROG_GET_FD_BY_ID
  bpf: Add BPF_MAP_GET_FD_BY_ID
  bpf: Add jited_len to struct bpf_prog
  bpf: Add BPF_OBJ_GET_INFO_BY_FD
  bpf: Test for bpf ID
