Differences

Regular

• Changed between 5.19 and 6.2 ⚠️

  • Param removed. enum btf_kfunc_type type
  • Param reordered. btf, prog_type, type, kfunc_btf_id ➡️ btf, prog_type, kfunc_btf_id
  • Return type changed. bool ➡️ u32 *
• Changed between 6.2 and 6.5 ⚠️

  • Param added. const struct bpf_prog *prog
  • Param removed. enum bpf_prog_type prog_type
