Hi Vishal,

I don't think there is any need to resend because of this.
But, for future reference, these days it is preferred to put changelog
information, such as the above two paragraphs, below the scissors ("---").

This way they are present in mailing list archives and so on.
But are omitted from git history (because the patch description is
truncated at the scissors).
