I have moved this to "fix committed", can someone verify that this patch
will be backported to the Trusty 3.13 series kernel, or do I need to
take any additional steps? I am not sure what my responsibility is in

** Changed in: linux (Ubuntu Trusty)
Status: In
Thanks Tim for the clarification. I will not make any more status
changes.
