These are minor robustness enhancements on top of v8 of the patchset [PATCH v8 00/50] linux: towards virtio-1 guest support http://mid.gmane.org/1417449619-24896-1-git-send-email-mst@xxxxxxxxxx As that one seems stable and actually seems to work well for people, I'm not respinning it anymore. The main motivation is to prevent us accidentally supporting bad configurations, such as legacy balloon on top of virtio 1.0 transport. The point is that if we happen to support them mistakenly, we'll have trouble backing out in future. This will also help make sure hypervisors don't do silly things. Changes from v2: Check finalize_features return status on resume. This shouldn't normally fail, but checking can't hurt. Michael S.
