Hi Vicenc,
I have not seen a reply to your email about this patch. Unfortunately
(or fortunately depending on your perspective) most of us were on vacation
last week and are just now catching up. We have not forgotten and will
start discussions next week.
Thanks for taking the time to submit the patch. Talk to you next week.
