cb56ecae4c docs: filesystems: vfs: correct flag name
There is no flag REMAP_CAN_SHORTEN.  Commit eca3654e3c ("vfs: enable
remap callers that can handle short operations") that introduces this
text also introduces the flag REMAP_FILE_CAN_SHORTEN.  Change the name
in the documentation accordingly.

c69f22f25f Replace HTTP links with HTTPS ones: Documentation/filesystems
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
          If both the HTTP and HTTPS versions
          return 200 OK and serve the same content:
            Replace HTTP with HTTPS.

8151b4c8be mm: add readahead address space operation
This replaces ->readpages with a saner interface:
 - Return void instead of an ignored error code.
 - Page cache is already populated with locked pages when ->readahead
   is called.
 - New arguments can be passed to the implementation without changing
   all the filesystems that use a common helper function like
   mpage_readahead().

ec23eb54fb docs: fs: convert docs without extension to ReST
There are 3 remaining files without an extension inside the fs docs
dir.

Manually convert them to ReST.

In the case of the nfs/exporting.rst file, as the nfs docs
aren't ported yet, I opted to convert and add a :orphan: there,
with should be removed when it gets added into a nfs-specific
part of the fs documentation.

ee5dc0491c docs: filesystems: vfs: Render method descriptions
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.

af96c1e304 docs: filesystems: vfs: Convert vfs.txt to RST
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.
