Dave, this patch is for net, since it fixes an issue in the current code 
(actually it relates to a patch
that was merged after 3.14-rc7, so it would eventually might go to 
-stable too). The author wasn't very
familiar with the exact differences/nature of net vs. net-next, so it 
might created some confusion here, I'v
sent him few private notes to explain how things go...

Or.
