Michael S. Tsirkin 2d61ba9503 virtio: order used ring after used index read ... On SMP guests, reads from the ring might bypass used index reads. This causes guest crashes because host writes to used index to signal ring data readiness. Fix this by inserting rmb before used ring reads. Signed-off-by: Michael S.
