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,
