-Additionally, there are the ``#[test]`` tests. These can be run using the
-``rusttest`` Make target::
+These are userspace tests that can be built and run in the host (i.e. the one
+that performs the kernel build) using the ``rusttest`` Make target::
make LLVM=1 rusttest
-This requires the kernel ``.config``. It runs the ``#[test]`` tests on the host
-(currently) and thus is fairly limited in what these tests can test.
