Differences

Regular

• Changed between 6.2 and 6.5 ⚠️

  • Param added. int insn_idx
  • Param added. int clone_ref_obj_id
  • Param removed. struct bpf_call_arg_meta *meta
  • Param reordered. env, regno, arg_type, meta ➡️ env, regno, insn_idx, arg_type, clone_ref_obj_id
• No changes between 6.5 and 6.8 ✅
