So you send the same? Or something new? Please provide proper changelog
and mark patches as v2/v3 or RESEND.

But anyway this cannot be RESEND as I explicitly asked for fixing.

<form letter>
This is a friendly reminder during the review process.

It seems my or other reviewer's previous comments were not fully
addressed. Maybe the feedback got lost between the quotes, maybe you
just forgot to apply it. Please go back to the previous discussion and
either implement all requested changes or keep discussing them.

Thank you.
</form letter>

Best regards,
Krzysztof

Sorry, have sent the same patch again. As I need to post one patch alone which got
missed due to internal technical issue. Next time onwards will make sure to mark the
patches as V2/V3 or RESEND accordingly.
