[Qemu-devel] [PULL 2/8] s390-virtio: use common features


From: Cornelia Huck
Subject: [Qemu-devel] [PULL 2/8] s390-virtio: use common features
Date: Fri, 8 May 2015 11:08:29 +0200

We used to avoid enabling event_idx for virtio-blk devices via
s390-virtio, but we now have a workaround in place for guests trying
to use the device before setting DRIVER_OK. Therefore, let's add
DEFINE_VIRTIO_COMMON_FEATURES to the base device so all devices get
those common features - and make s390-virtio use the same mechanism
as the other transports do.
