Hm. In "old good days" there were 3 independent kernel modules,
named raid4, raid5 and raid6. Later on, they got merged into one
since they share quite alot of the code, and has only a few specific
parts. Now you're trying to separate them back somewhat....

What's your goal? What's the problem you're trying to solve?
