You can use :doc: syntax for linking to other docs with custom anchor text,
like:
```
:doc:`userspace debugging guide <userspace_debugging_guide>`
```
(note the file suffix omission).
Better yet, specify the full doc path (e.g.
`Documentation/debugging/userspace_debugging_guide.rst`) and Sphinx will
generate the anchor text with target doc's title.

Please split general debugging advice into its own doc (e.g. at
general-advice.rst). Most other docs have index.rst only for toctree
listing.

Sphinx complains about stray underscores:
Documentation/debugging/userspace_debugging_guide.rst:54: WARNING: Mismatch: both interpreted text role prefix and reference suffix.
I have to trim them:

-- When the code contains one of the :ref:`valid print statements <valid_dyndbg_prints_>`_ or when you have added multiple pr_debug() statements during development

- When timing is not an issue, meaning if multiple `pr_debug()` statements in the code won't cause delays
- When you care more about receiving specific log messages than tracing the pattern of how a function is called
Thanks.
