Hi,

I'm wondering if there are any more comments for this patch? I would
be happy to clarify anything that's unclear or improve the code if
needed.

I know it's pretty late, but it would be really great if this fix
could land before v6.2 is released, so I'd appreciate your help and
review.

Thank you,
Michał
