Please hold on. It is Friday evening here. First I cannot take the
time to articulate an answer you are requesting on the other thread
part. Second, the latest version of the patch has been sent from Pavan
a couple of hours ago, and you are proposing to commit it in a message
sent 29 minutes after the last version has been sent.

Let's cool down a bit and take some time for reviews, please. You still
have one week until the end of the commit fest anyway.

Thanks,
