Thanks for checking; and yes I forgot out-of-tree modules. When building them, Kbuild changes to their respective output directory so my suggestion had to fail for oot kmods.

I am not sure, if we can take your path, as 'readlink --relative-to' is only available in coreutils/Linux but coreutils are not a documented requirement for Linux builds (cp. Documentation/process/changes.rst), thus this would probably kill Linux builds on BSDs and Darwin/MacOS. But let me think about that a few days; and perhaps someone else comes up with an idea. Kind regards, Nicolas
