Maybe c:func: really works only in the headers. I have in my notes
:c:func:`tst_kvercmp()`. We already use in doc/* some :ref: e.g.
:ref:`struct tst_device` or :ref:`tst_brk`.

Interesting. For me works only :c:func:`TST_PROCESS_STATE_WAIT()` or
:c:func:`tst_brk()` when adding it into random file (e.g.
doc/maintainers/patch_review.rst). 

Anyway, thanks for taking care to link it.

Kind regards,
