assert.h is part of the userspace C. You can't use it in kernel code.

If you did the equivalent of an assert in the kernel, you'd panic the 
kernel if it was ever wrong.

As a rule bear in mind that kernel code (or any bare metal system code 
for that matter) written in C can't use anything from the C libraries, 
nor from any of the userspace C headers.

What is it that you're trying to do?
