Work from Tobin Harding:
Here is an updated version of the VFS doc conversion. This series
in no way represents a final point for the VFS documentation rather
it is a small step towards getting VFS docs updated. This series
does not update the content of vfs.txt, only does formatting.
Currently vfs.rst does not render well into HTML the method descriptions
for VFS data structures. We can improve the HTML output by putting the
description string on a new line following the method name.

As discussed at the linux-doc ML, while we'll still support
version 1.3, it is time to recommend a more modern version.
So, let's switch the minimal requirements to Sphinx 1.7.9,

Since Sphinx version 1.7, it is possible to use "-jauto" in
order to speedup documentation builds. On older versions,
while -j was already supported, one would need to set the
number of threads manually.
So, if SPHINXOPTS is not provided, add -jauto, in order to
speed up the build. That makes it *a lot* times faster than
without -j.
If one really wants to slow things down, it can just use:
make SPHINXOPTS=-j1 htmldocs

There are at least two cases where a documentation file was gone
for good, but the text still mentions it:
1) drivers/vhost/vhost.c:
the reference for Documentation/virtual/lguest/lguest.c is just
to give credits to the original work that vhost replaced;
2) Documentation/scsi/scsi_mid_low_api.txt:
It gives credit and mentions the old Documentation/Configure.help
file that used to be part of Kernel 2.4.x
As we don't want to keep the script to keep pinpoint to those
every time, let's add a logic at the script to allow it to ignore
valid false-positives like the above.

Call the script every time a make docs target is selected, on
a simplified check mode.
With this change, the script will set two vars:
$min_version - obtained from `needs_sphinx` var inside
conf.py (currently, '1.3')
$rec_version - obtained from sphinx/requirements.txt.
With those changes, a target like "make htmldocs" will do:
1) If no sphinx-build/sphinx-build3 is found, it will run
the script on normal mode as before, checking for all
system dependencies and providing install hints for the
needed programs and will abort the build;
2) If no sphinx-build/sphinx-build3 is found, but there is
a sphinx_${VER}/bin/activate file, and if
${VER} >= $min_version (string comparation), it will
run in full mode, and will recommend to activate the
virtualenv. If there are multiple virtualenvs, it
will string sort the versions, recommending the
highest version and will abort the build;
3) If Sphinx is detected but has a version lower than
$min_version, it will run in full mode - with will
recommend creating a virtual env using sphinx/requirements.txt,
and will abort the build.
4) If Sphinx is detected and version is lower than
$rec_version, it will run in full mode and will
recommend creating a virtual env using sphinx/requirements.txt.
In this case, it **won't** abort the build.
5) If Sphinx is detected and version is equal or righer than
$rec_version it will return just after detecting the
version ("quick mode"), not checking if are there any
missing dependencies.
Just like before, if one wants to install Sphinx from the
distro, it has to call the script manually and use `--no-virtualenv`
argument to get the hints for his OS:
You should run:
sudo dnf install -y python3-sphinx python3-sphinx_rtd_theme
While here, add a small help for the three optional arguments
for the script.

vfs.txt is currently stale. If we convert it to RST this is a good
first step in the process of getting the VFS documentation up to date.
This patch does the following (all as a single patch so as not to
introduce any new SPHINX build warnings)
- Use '.. code-block:: c' for C code blocks and indent the code blocks.
- Use double backticks for struct member descriptions.
- Fix a couple of build warnings by guarding pointers (*) with double
backticks .e.g ``*ptr``.
- Add vfs to Documentation/filesystems/index.rst
The member descriptions paragraph indentation was not touched. It is
not pretty but these do not cause build warnings. These descriptions
all need updating anyways so leave it as it is for now.

With Sphinx 2.0 (or prior versions with the deprecation warnings fixed) the
docs build fails with:
Documentation/gpu/i915.rst:403: WARNING: Title level inconsistent:
Global GTT Fence Handling
~~~~~~~~~~~~~~~~~~~~~~~~~
reST markup error:
Documentation/gpu/i915.rst:403: (SEVERE/4) Title level inconsistent:
I "fixed" it by changing the subsections in i915.rst, but that didn't seem
like the correct change. It turns out that a couple of i915 files create
their own subsections in kerneldoc comments using apostrophes as the
heading marker:
Layout
''''''
That breaks the normal subsection marker ordering, and newer Sphinx is
rather more strict about enforcing that ordering. So fix the offending
comments to make Sphinx happy.
(This is unfortunate, in that kerneldoc comments shouldn't need to be aware
of where they might be included in the heading hierarchy, but I don't see
a better way around it).
