Of course not. When I developed and tested this series, I always compile the kernel twice, maybe more :-(, to do comparisons between the result from guess and result from prologue to determine whether prologue is effective. Also, the guess_unwinder might be more reliable if function_graph is enabled, because prologue_unwinder may stop by strange code flow. If you think it is meaningless, I'll remove it in the next version. It doesn't affect other patches in this series.
Thanks,
Jinyang
