I've seen the test to pass most of the time but that it still fails depending on the load is annoying and requires checking the results. So even if it's probably a workaround (not sure we can make it 100% reliable without peeking into the internals) it's making things better. Acked-by: David Sterba <dsterba@xxxxxxxx>
