The root document usually has a special :ref:`genindex` link to the generated index. This is also the case for Documentation/index.rst. The other index.rst files deeper in the directory hierarchy usually don't. For SPHINXDIRS builds, the root document isn't Documentation/index.rst, but some other index.rst in the hierarchy. Currently they have a ".. only::" block to add the index link when doing SPHINXDIRS html builds. This is obviously very tedious and repetitive. The link is also added to all index.rst files in the hierarchy for SPHINXDIRS builds, not just the root document. Put the boilerplate in a sphinx-includes/subproject-index.rst file, and include it at the end of the root document for subproject builds in an ad-hoc source-read extension defined in conf.py. For now, keep having the boilerplate in translations, because this approach currently doesn't cover translated index link headers.

Driver implementer's API guide
|
|
==============================
|
|
|
|
The kernel offers a wide variety of interfaces to support the development
|
|
of device drivers. This document is an only somewhat organized collection
|
|
of some of those interfaces — it will hopefully get better over time! The
|
|
available subsections can be seen below.

General information for driver authors
|
|
======================================
|
|
|
|
This section contains documentation that should, at some point or other, be
|
|
of interest to most developers working on device drivers.
