For its part, academia has provided tools to automate the mindless and 
error-prone refactoring which Bart points to. I'm mainly thinking of LLVM 
and Ocaml. (I'm not a computer scientist.)

But I fear that code transformation tools lie beyond the skill and ability 
of those of us who submit spelling fixes.

So the tools need to be made more usable in this setting. Corporate users 
of kernel code who happen to have their own IDE products (Microsoft, 
Google, etc.) have an opportunity here.
