That being said -- and I do say this as the original author of this code --
this should be reduced to the maximum extent possible to a (minimal) set of
#ifndef __KERNEL__, which should be localized as much as possible. The actual
user space components, even such a thing as a simple #include, should be moved
to a separate user space header.

But pretty please do leave the ability to debug the algorithms in user space.
This is hard code to write and debug; it is not just about regression testing.
