It's pretty simple :) Do you think putting this line anywhere, in any file, does it? That would be crazy. How about a book, e.g. describing a patch submission process (but not a copy of kernel's Documentation). The same? Also - in all countries? Most of them? Come on. Then why would we need the Signed-off-by? >From my perspective, the SPDX-License-Identifier is only meaningful when the file is actually a part of the kernel, or if, at least, it's been presented for merge, with Signed-off-by etc. -- Krzysztof Hałasa Sieć Badawcza Łukasiewicz Przemysłowy Instytut Automatyki i Pomiarów PIAP Al.
