I decided to resend again because I was not sure that the previous
patchset was not lost. I also wanted to ask David to review and explain
about the new API. I in any case did not ignore your question about
changing the type of the parameter.
I guess I was wrong when I sent the whole patchset again. Sorry.

I think you misunderstood me. I didn't mean to rush you.
