Subject: [PATCH v4 bpf-next 0/2] Add array support to btf_struct_access

This series adds array support to btf_struct_access().
Please see individual patch for details.

v4:
- Avoid removing a useful comment from btf_struct_access()
- Add comments to clarify the "mtrue_end" naming and
  how it may not always correspond to mtype/msize/moff.

v3:
- Fixed an interpreter issue that missed accounting
  for insn->off

v2:
- Fix a divide-by-zero when there is empty array in
  a struct (e.g. "__u8 __cloned_offset[0];" in skbuff)
- Add 'static' to a global var in prog_tests/kfree_skb.c

Martin KaFai Lau (2):
  bpf: Add array support to btf_struct_access
  bpf: Add cb access in kfree_skb test
