Michael S. Tsirkin 19a0ff53ff virtio_pci: fix virtio spec compliance on restore ... commit 6fbc198cf6 upstream. On restore, virtio pci does the following: + set features + init vqs etc - device can be used at this point! + set ACKNOWLEDGE,DRIVER and DRIVER_OK status bits This is in violation of the virtio spec, which requires the following order: - ACKNOWLEDGE - DRIVER - init vqs - DRIVER_OK This behaviour will break with hypervisors that assume spec compliant behaviour. It seems like a good idea to have this patch applied to stable branches to reduce the support butden for the hypervisors. Cc: Amit Shah <amit.shah@redhat.com> Signed-off-by: Michael S.
