[PATCH v2 0/8] docs: Cleanup kernel-doc and fix literal block handling

[Jonathan Corbet]

So once upon a time I set out to fix the problem reported by Tobin wherein
a literal block within a kerneldoc comment would be corrupted in
processing.  On the way, though, I got annoyed at the way I have to learn
how kernel-doc works from the beginning every time I tear into it.

As a result, seven of the following eight patches just get rid of some dead
code and reorganize the rest - mostly turning the 500-line process_file()
function into something a bit more rational.  Sphinx output is unchanged
after these are applied.  Then, at the end, there's a tweak to stop messing
with literal blocks.

If anybody was unaware that I've not done any serious Perl since the
1990's, they will certainly understand that fact now.

Changes in v2:
  - Fix up old coding-style ugliness as I move the code
  - Handle ".. code-block::" literals as well.  This fixed
    the formatting in dev-tools/kselftest.rst.
