Yeah, right, so it is embarrasingly so :-) I wonder how I missed ths during the review. Thanks for spotting this one out. Are you saying that I should merge the patches into a single one? Perhaps you could send me the merged patch if so? If you agree, please send only that patch. I'll send v4 of my patch set after 4.17 pull request. /Jarkko
