They are based on the tests sent back them, the ones that were not included (reasons in that thread). This series changes: * Delete need to export the ugly function in virtio_ring, now all the code is added in tools/virtio (except the one line fix). * Add forgotten uses of vhost_vq_set_backend. Fix bad usage order in vhost_test_set_backend. * Drop random reset, not really needed. * Minor changes. The first patch of this patchset ("vhost: Not cleaning batched descs in VHOST_SET_VRING_BASE ioctl") should be squashed with ("vhost: batching fetches") (currenlty, commit e7539c20a4a60b3a1bda3e7218c0d2a20669f357 in mst repository vhost branch). Thanks! Changes from v2: * Squashed commits with fixes. * Back to plain vring_* Changes from v1: * Different base, since branch was force-pushed. * Using new vring_legacy_*, as base uses them now.
