Indeed, thanks for the hint. > Iff we would add 'obj-y += kunit/' in lib/Makefile we'd have to adjust the > hooks.o line in lib/kunit/Makefile appropriately. I'll go with the 'obj-y += kunit/' solution for now. It keeps the special logic for hook.o in a single place, gets rid of a duplicate comment and is easier to understand. <snip>
