It's probably best to > take vfio-ccw through the kvm-s390 tree. Beside the fixes for former comments form you and Alex, I will also do the following stuff in the next version: 1. Remove the "RFC" tag from the mail subject. 2. Cc the s390 CIO layer maintainers for patch 1 and 2: Sebastian Ott Peter Oberparleiter 3.
