Could you split to a few distinct patches?
And, for each of them, give more detailed descriptions in the patch
itself, not digested in a single subject line. In that way, people
can follow the changes in more logical way.
After getting the split patches, I'll review more on them.
thanks,
Takashi

Hello,
I just resend the patch split in four with correct subject and body.
Let me know, if you have other advices.
Thanks
