Merge branch 'virtio-next' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux
Pull virtio changes from Rusty Russell:
"New workflow: same git trees pulled by linux-next get sent straight to
Linus. Git is awkward at shuffling patches compared with quilt or mq,
but that doesn't happen often once things get into my -next branch."

lguest: fix occasional crash in example launcher.
virtio-blk: Disable callback in virtblk_done()
