The stable guys don't maintain every tree indefinitely, usually only for
a couple of releases after the next mainline release or something (I
suppose you can find the official policy online somewhere). Presumably
these fixes came too late for the 3.8.y branch.

Longterm stable trees are an exception and get longer backports, I don't
think 3.8 is one of those though.

If anyone wants further backports then they will need to speak to the
Linux stable maintainers, although they should probably expect a "this
stable tree is now closed" type response for 3.8.

Or perhaps the above link implies that Canonical are supporting their
own LTS of Linux 3.8.y -- in which case the request should be made to
whoever that maintainer is.

Ian.
