Is that right? Or OK if so? Perhaps I'm mis-understanding the "$(if $(KBUILD_SRC),*.py)" statement intent?

Is that right? Or OK if so? As you noticed in 5/5, files listed in $(extra-y) are cleaned up. So, I removed the now redundant $(obj)/constants.py from 'clean-files'. > Perhaps I'm mis-understanding the "$(if $(KBUILD_SRC),*.py)" statement > intent? $(if $(KBUILD_SRC),*.py) will clean *.py only for out-of-tree build. '*.py' files in the build directory are symbolic links. '*.py' files in the source directory are check-in source files. > As long as you're content with the result, and it's understood: > > Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com> -- Best Regards Masahiro Yamada

Currently, Kbuild descends from scripts/Makefile to scripts/gdb/Makefile just for creating symbolic links, but it does not need to do it so early. Merge the two descending paths to simplify the code.
