Am I close? And do that with the headers in tools/ which do not have the new changes and see if they still build? Or? Alternatively, we can always go back to keeping the headers in sync with those in tools/ and f'get about it. Thoughts? Thx. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
