Alice Ryhl da80f4ffb0 list_lru: expand list_lru_add() docs with info about sublists 
The documentation for list_lru_add() and list_lru_del() has not been
updated since lru lists were originally introduced by commit a38e408248
("list: add a new LRU list type").  Back then, list_lru stored all of the
items in a single list, but the implementation has since been expanded to
use many sublists internally.

Thus, update the docs to mention that the requirements about not using the
item with several lists at the same time also applies not using different
sublists.  Also mention that list_lru items are reparented when the memcg
is deleted as discussed on the LKML [1].

Also fix incorrect use of 'Return value:' which should be 'Return:'.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
