Actually - that series should also fix you problem and avoid the need
for both patches in this series.  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
