David,

I think this patch (http://patchwork.ozlabs.org/patch/164100/) was erroneously flagged as "Changes 
Requested". Despite my suggestion to add a "possible typo" warning, I acked the patch and so do Jay. 
We eventually decided not to add the "possible typo" warning, so the patch should be accepted.

Thanks,

	Nicolas.
