Hi,

Thanks for having taken this patch promptly.
Given that the warnings is issued more than 148000 and thus tend
to drown the other, more useful, warnings in the noise, I think
it would be a good thing to have this patch already in 4.16.
I should have put this clearly in the patch description.

Best regards,
