We need to fix this regression for 2.6.36.  Not sure what else I need to
do to get this on your radar.  It's a pretty significant show-stopper
for 2.6.36 guests that use virtio-blk with a udev enabled distro.

Here is a reference to my original patch (which Ryan and hch have both
reviewed): https://patchwork.kernel.org/patch/165571/

Thanks,
Mike
