SeongJae Park 47d63d7a39 Docs/RCU/rculist_nulls: Fix text about atomic_set_release()
The document says we can avoid extra _release() in insert function when
hlist_nulls is used, but that's not true[1].  Drop it.

SeongJae Park d186204a98 Docs/RCU/rculist_nulls: Fix hlist_[nulls]_head field names of 'obj'
The example code snippets on rculist_nulls.rst are assuming 'obj' to
have the 'hlist_head' or 'hlist_nulls_head' field named 'obj_node', but
a sentence and some code snippets are wrongly calling
'obj->obj_node.next' as 'obj->obj_next', or 'obj->obj_node' as 'member'.
Fix it.

SeongJae Park 3f831e38ce Docs/RCU/rculist_nulls: Fix trivial coding style
Lookup example of non-hlist_nulls management is missing a semicolon, and
having inconsistent indentation (one line is using single space
indentation while others are using two spaces indentation).  Fix the
trivial issues.

Akira Yokosawa 404147faaa docs: Update RCU cross-references as suggested in doc-guide
The RCU documentation contains old-style cross references which
do not follow the best practices outlined in doc-guide/sphinx.rst.
In addition, some of the cross references use URLs that should be replaced
by pathnames.

Update all of these cross references and adjust the surrounding words.

Summary of changes:

  - out-of-date plaintext file names (*.txt) -> *.rst
  - references by :ref: tags -> path names of *.rst
    * use relative paths to .rst files under the RCU/ subdirectory
    * use abs paths of Documentation/xxx for other .rst files
  - references by URL under https://www.kernel.org/ -> paths of *.rst
  - adjust surrounding words of some of updated references.

Note:
  The automarkup.py script interprets references via "*.txt" as if they
were via "*.rst", so the *.txt -> *.rst changes should be regarded as
cleanups rather than bug fixes.

Mauro Carvalho Chehab 2d9c318bfd docs: RCU: Don't duplicate chapter names in rculist_nulls.rst
Since changeset 58ad30cf91 ("docs: fix reference to core-api/namespaces.rst"),
auto-references for chapters are generated. This is a nice feature, but
has a drawback: no chapters can have the same sumber.

So, we need to add two higher hierarchy chapters on this document,
in order to avoid such duplication.

Fixes: 58ad30cf91 ("docs: fix reference to core-api/namespaces.rst")
