Re: [PATCH 3/3] tools/virtio: add --features-array switch

This is expected, not a bug in the test.
The clear_user() start-address issue in VHOST_GET_FEATURES_ARRAY is the
pre-existing kernel bug that the separately posted fix [1] (Acked-by:
Eugenio) addresses. Patch 3 here is its regression test, so it
intentionally aborts in verify_get_features_array() against an unfixed
kernel and passes once [1] is applied; the dependency is noted in the
cover letter.
