There is no warning. I have added this new document in a new toctree in the
kselftest.rst, as you can see in the hunk below.

Since this new page is specific to kselftest, I think listing it on the
kselftest page makes the most sense and will make it easier to find.

Do you want the new file to be listed in both places (ie kselftest.rst and
index.rst)? It will show up in the index.rst next to kselftest rather than
inside it.

Another option would be to do like kunit and create a directory for kselftest
and have an index.rst there to point to both the current kselftest.rst and the
new document. Structure-wise that would probably be the best approach.

Ack.
