Thank you for this series.

Please note that we're also observing this issue on 6.1.
I think this series is a good candidate for a back port (slightly complicated by
the fact that various refactors have happened since).

For me, it's working fine so far on master, and I've also done my own back port
to 6.1 and am currently testing both. An official back port once finalised
could be useful, though :-)


Cheers,
