This reverts commit 99e8927d8a4da8eb8a8a5904dc13a3156be8e7c0: proposed API isn't supported on all transports but no effort was made to address this. It might not be hard to fix if we want to: maybe just rename size to size_hint and make sure legacy transports ignore the hint. But it's not sure what the benefit is in any case, so let's drop it. Fixes: 99e8927d8a4d ("virtio_vdpa: support the arg sizes of find_vqs()") Signed-off-by: Michael S.
