And the same question for https://lists.xenproject.org/archives/html/xen-devel/2017-02/msg00625.html and https://lists.xenproject.org/archives/html/xen-devel/2017-02/msg00754.html (And while I am at it, I took https://lists.xenproject.org/archives/html/xen-devel/2017-01/msg00833.html to Xen tree, hope you don't mind) -boris
