Thanks for your time!

About the changelog, I admit that it makes little improvement to the whole,
It is a so *short* function, I also don't think it can produce any visible
improvement through any kernel test tools. But as you can see, the redundant
intermediate operation indeed exists. There's no reason to let it exist any
more - make code clear and easy to understand if possible.
