This works, but it doesn't support auto loading. For instance when libvirt checks for VFIO support it looks for /dev/vfio/vfio, which currently doesn't exist unless the vfio module is loaded. By converting the control device to a misc driver and reserving a static minor, we can enable auto loading. Reserving the minor is a prerequist to that conversion. Minor 196 is unused by anything currently in the kernel. Suggested-by: Paolo Bonzini Signed-off-by: Alex Williamson Acked-by: Greg Kroah-Hartman --- Reading git-diff-tree failed
