I dislike it generally, but it exists so <shrug>. I know others feel
more strongly about it being un-kernely and the wrong way to use sysfs.

Here I was remarking how the example in the cover letter made the mdev
part seem totally pointless. If it is pointless then don't do it.

Remember we have stripped away the actual special need to use
mdev. You don't *have* to use mdev anymore to use vfio. That is a
significant ideology change even from a few months ago.
