Currently, the rcu_torture_current variable remains non-NULL until after all readers have stopped. During this time, rcu_torture_stats_print() will think that the test is still ongoing, which can result in confusing dmesg output. This commit therefore NULLs rcu_torture_current immediately after the rcu_torture_writer() kthread has decided to stop, thus informing rcu_torture_stats_print() much sooner. 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 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.
