/dev/vfio/vfio has 600 permissions, should be 666 (fix is queued for 3.10)

/dev/vfio/vfio has 600 permissions, but in order for libvirt to be able to use it with default config, it needs to be 666. 3.10 already has a fix queued up, could it be backported to current F19?

vfio: Set container device mode
Minor 0 is the VFIO container device (/dev/vfio/vfio). On it's own
the container does not provide a user with any privileged access. It
only supports API version check and extension check ioctls. Only by
attaching a VFIO group to the container does it gain any access. Set
the mode of the container to allow access.

vfio: fix crash on rmmod
We can grab those, but is there a reason they aren't CC'd to stable? Particularly the second one?
Alex, see Comment #2, is there a reason these VFIO bits aren't heading for kernel stable tree?
I don't see that they meet the rules for stable. It's not a critical bug as far as the kernel is concerned. Note that both of these are going in during the 3.10 development phase, so there is no case of a released upstream kernel including one without the other.

Ah. I see. I should have looked more first. I thought the rmmod fix was a stand-alone issue.
I've grabbed both for F19.
