Uladzislau Rezki (Sony) a78d4a2a10 kvfree_rcu: Refactor kfree_rcu_monitor()
Currently we have three functions which depend on each other.
Two of them are quite tiny and the last one where the most
work is done. All of them are related to queuing RCU batches
to reclaim objects after a GP.

1. kfree_rcu_monitor(). It consist of few lines. It acquires a spin-lock
   and calls kfree_rcu_drain_unlock().

2. kfree_rcu_drain_unlock(). It also consists of few lines of code. It
   calls queue_kfree_rcu_work() to queue the batch.  If this fails,
   it rearms the monitor work to try again later.

3. queue_kfree_rcu_work(). This provides the bulk of the functionality,
   attempting to start a new batch to free objects after a GP.

Since there are no external users of functions [2] and [3], both
can eliminated by moving all logic directly into [1], which both
shrinks and simplifies the code.

Also replace comments which start with "/*" to "//" format to make it
unified across the file.

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 Restructured Text 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.
