Subject: VIRTIO_BLK_F_CONFIG_WCE removed from virtio 1.0?
I guess we were a bit overzealous in removing VIRTIO_BLK_F_FLUSH aka VIRTIO_BLK_F_WCE. The VIRTIO_BLK_F_CONFIG_WCE is a useful feature and should be preserved in order to achieve feature parity between 0.9 and 1.0. Sorry for commenting on this so close to the deadline, but I think this is a blocker. :( I'll send a patch shortly. Paolo
