I don't know what the reference to 4.4.1 is about there. This patch
hasn't been merged upstream, and as far as I can tell no alternative fix
has either. Eric Biederman disputes that it's really a bug at all, which
may explain why it wasn't merged.

So if we still consider this a vulnerability, I think we'll need to keep
the patch.
