The only way to be able to use a patch for each driver would be to keep the original grant-, event- and xenbus-interfaces and add the new ones taking xenhost * with a new name. The original interfaces could then use xenhost_default and you can switch them to the new interfaces one by one. The last patch could then remove the old interfaces when there is no user left. Juergen
