Just to ask a general opinion:

Am I right that it's ok for kernel code to be organized how we (the 
developers) see fit as long as we don't break userspace or hardware in 
the process?

So long as we function properly, should userspace care about how our 
source code is structured?

I'm thinking yes, but it might be fruitful to see an answer archived on 
the list.
