This commit creates counters in the rcu_torture_one_read_state_updown structure that check for a call to ->up_read() that lacks a matching call to ->down_read(). While in the area, add end-of-run cleanup code that prevents calls to rcu_torture_updown_hrt() from happening after the test has moved on. Yes, the srcu_barrier() at the end of the test will wait for them, but this could result in confusing states, statistics, and diagnostic information. So explicitly wait for them before we get to the end-of-test output. [ paulmck: Apply kernel test robot feedback. ] [ joel: Apply Boqun's fix for counter increment ordering. ] Signed-off-by: Paul E.

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.
