Okay, I wish this chain-reply would make people easy to find the
previous comments, but actually it is little mess now. I would give
up this way to send patchset :)

Yeah, it's quite big now, I would like to back the patchset to previous
format, like:

---> [PATCH v6 00/17] Cover letter
|----> [PATCH v6 01/17]
|----> [PATCH ......]
|----> [PATCH v6 05/17]
|----> [PATCH v7 05/17]
|----> [PATCH ......]
|----> [PATCH v6 17/17]

Is it right, and can resend the v6 to fix this chain-reply issue with
RESEND flag ([PATCH RESEND v6 ...]) ?

---> [PATCH RESEND v6 00/17] Cover letter
|----> [PATCH RESEND v6 01/17]
|----> [PATCH ......]
|----> [PATCH RESEND v6 05/17]
|----> [PATCH v7 05/17]
|----> [PATCH ......]
|----> [PATCH RESEND v6 17/17]

Thanks :-)
