Depends on what you're expecting from a (stable) kernel. The patch description mentions what happens when a system deals with a lot of other ipv6-systems and that problem is easy to exercise and to value. Rating the information leak is harder, some people even won't understand that this might be a problem. And now look at which kernel-versions are now used in new devices (likely something <= 3.10, which is more than two years old), how long they will be used, and make a guess about IPv6 usage in 5 years. Anyway, I've no insights about all the politics happening in the background (e.g. stuff like the LTSI tree) and I've just wanted raise awareness about that (imho important) patch series.
