Can you please test it? Hi Christoph, thanks for looking into this. You're right, this series fixes both issues. The problem I see though is that it relies on legacy IO path removal - for v5.0 and beyond, all fine. But backporting that to v4.17-v4.20 stable series will be quite painful. My fixes are mostly "oneliners". If we could get both approaches upstream, that'd be perfect! Cheers, Guilherme
