I don't see how this is a feature. It's a bug fix at the most to be
honest, upstream requires CFQ at runtime instead of Deadline, and
we're fixing that runtime dep.

Also, I did run this past foundations a couple of months ago where I
asked if there could be any issues for Kubuntu, and off the top of
their head they could not think any. But as Harald mentioned, a bug
should be opened for the foundations team to investigate switching
back to CFQ.
