Nah, i do not think it's ever too late to care. Example: arch/i386 - arch/x86_64/ was very messy for many, many years and we turned it around and can be proud of arch/x86/ today - but i guess i'm somewhat biased there ;-) In my experience it's entirely possible to turn a messy gooball into something you can be proud of - it's all reversible. Start small, with the core bits you care about most - then extend those concepts to other areas of the code base, gradually. There might be subsystems that will never turn around before becoming obsolete - that's not a big problem. Thanks, Ingo
