Please review the patch :) Thanks.

lgtm.

Now would be a good time to try trybot, just for the experience.

Thanks for lgtm.
I have tried it. I guess I do not have permission of trybot. Test win, win_rel
seems to be pending.


"If you do not have an @chromium.org email address, or wish to use a different
email address;
Ask someone you're working with (a frequent reviewer, for example) to send email
to committers@chromium.org nominating you for tryjob access. 
You must provide an email address and at least a brief explanation of why you'd
like access. You can also ask for an @chromium.org address at this time."

Congratulation! You are a frequent reviewer. :)
Can I ask to you nominating me for try job access and @chromium.org ?

Do you want a chromium.org email address?

If I can do myself something to request chromium.org for getting permission next
time, Yes. I need.
Actually, I do not want to bother you. :) If you are fine, I don't need email
address now.
