Thanks for your kindly suggestion.
Actually I have to think more about how to express in English
as a foreign speaker...

But you are absolutely right ;) this commit is actually confusing and I will
do my best to write commit subject and message clearly...

If something wrong like this, please kindly point out and I will update immediately :)

Anyway, I will send patch v2 of this commit for Greg to merge...

Thanks,
Gao Xiang
