It probably doesn't. If I drop the "bool" line, it will become non-configurable calculated Kconfig value, convenient to use everywhere. All the rest will stay exactly the same. It's nice to not have to do "if defined(DEBUG_INFO_BTF) && defined(MODULES) && defined(PAHOLE_HAS_SPLIT_BTF)" checks, but rather a simple "ifdef CONFIG_DEBUG_INFO_BTF_MODULES". Does that work?
