Yes, in 3.2, so it is old enough.  If this were a regression in 3.3, I'd push
it for 3.4.

Well, it was late for the 3.4 merge window and it wasn't clear whether or
not the patch was a regression fix at that time.  It is not very
straightforward and in my opinion it should be tested a bit wider before it
goes into -stable.

So as I said, v3.5 is the target with whatever -stable trees are relevant at
the time the patch is merged.

Thanks,
Rafael
