As Dario mentioned in the email, the title should be changed and the
email should be a new email thread, instead of a forward email.

A reference to the format of sending a newer version of patch can be
found at https://www.mail-archive.com/xen-devel@xxxxxxxxxxxxx/msg60115.html

In the commit message, you can add
---
Changes to the v1
---
to state the changes made from the previous versions.
You can also refer to the previous discussion with a link in that section..
This makes the reviewers' life easier.
The change log won't be committed.

Could you please send another version after resolving the concerns
raised by Dario and me?

Don't hesitate to ping me if you have any question.

Thanks,

Meng
