It would be better to reorder the functions in each file so that
you don't need forward declarations. This generally makes reading
the code easier because it is what people expect to see. It
also makes it clearer where you have possible recursions in the code.

The tracing functions are rather obscure. I would recommend dropping
them all for now, in order to get the code included. At a later
stage, you can add standard trace points.

In general, don't wrap standard kernel API functions with your
own abstractions, just use kmalloc here for instance.
It is rather annoying when you want to understand code and it
calls nonstandard functions that do almost the same that the
standard API does.
If you find something lacking in the existing API, feel free
to make suggestions for improving it. Either it is a good idea
and everyone will be happy about the useful new interface,
or it is a bad idea and you shouldn't be using it in the first
place.
