Oops, right! And this is caused by below callchain set_current_kprobes->is_IF_modifier->skip_prefixes ->inat_get_opcode_attribute However, this looks very wired that the copied instruction (ainsn->insn) is analyzed at every probe hit. I think we should add a bit flag indicating IF modifier to the ainsn. Thank you for reporting!! -- Masami HIRAMATSU IT Management Research Dept.
