Citation from my response to Al: But why does the code that calls it need to be modular? I get why the actual test cases should be modular, but the core test runner is small and needs a lot of kernel internals. Just require it to be built-in and all this mess goes away. That being said some of this stuff, like get_fs_type / put_filesystem or replace_fd seem like the wrong level of abstractions for something running tests anyway.
