Process is not like that. You first review internally, then you send.
After you sent and receive comments, you respond to these comments.

And what granularity do you need? Why mhz does not work?

Sorry, but I cannot respond that way. We discuss inline, so I have
entire picture, not some parts of message semi-quoted here. I don't
remember what was there and I am not going to keep looking for that.

You need to adjust to mailing list discussion style, not introduce the
others. I have just way too many other patches to deal with, so
implement the feedback or respond properly.

Best regards,
