Is this an already applied patch that you want accepted into the -stable tree?

If so, which tree(s)? Sorry, yes. It is current in 3.16.y, and we would like it queued up for 3.14.y and 3.15.y stable trees. I got a bit confused when I went to submit this to stable and saw that networking stable patches were handled differently that other stable patches. I tried to make my request clear by writing that first paragraph in the patch description, but I probably just muddied the water instead. It is just easier, when the developers tell me to begin with that a patch needs to go into stable when they first submit the patch. Which was not the case for this patch, grrr.
