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.
