Please drop my ack from this, this isn't the patch I acked originally
and we were having a conversation as recently as yesterday on v4 about
this patch because Rob didn't like this approach. His suggestion is
better than the one I gave on v4 that you have used here.

Please give it a few days between resubmissions, and do not send new
versions of a series every day. It is very confusing to have different
conversions on three versions of this patch in my inbox all at the same
time.

Thanks,
Conor.
