The rcutorture module has an rcu_torture_writer task that repeatedly performs writes, synchronizations, and deletes. There is a corner-case check in rcu_torture_writer() wherein if nsynctypes is 0, a warning is issued and the task waits to be stopped via a call to torture_kthread_stopping() rather than performing any work. There should be a return statement following this call to torture_kthread_stopping(), as the intention with issuing the call to torture_kthread_stopping() in the first place is to avoid the rcu_torture_writer task from performing any work. Some of the work may even be dangerous to perform, such as potentially causing a #DE due to nsynctypes being used in a modulo operator when querying for sync updates to issue. This patch adds the missing return call. As a bonus, it also fixes a checkpatch warning that was emitted due to the WARN_ONCE() call using the name of the function rather than __func__.

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.
