This patch allows virtio-blk to release its block queue lock while kicking the host. This improves scalability on SMP guests who would otherwise spin on the lock while another vCPU is kicking the host. This approach can be used for other virtio devices too. It simply splits the virtqueue_kick() operation into a prepare step which requires that the lock be held and the actual notify step which

Hello, These patches are an initial attempt at supporting hibernation for virtio drivers. The default configuration of event_index=on doesn't work; i.e. restore from a hibernated image only works if the devices have event_index support turned off. I have not yet dug into this, but is most likely due to some state not being sync'ed. This could be related to the hack that is patch 3.
