[ Upstream commit fd13fe16db0d82612b260640f4e26f6d9d1e11fd ] Currently, in CONFIG_RCU_BOOST kernels, if the rcu_torture_init() function's call to cpuhp_setup_state() fails, rcu_torture_cleanup() gamely passes nonsense to cpuhp_remove_state(). This results in strange and misleading splats. This commit therefore ensures that if the rcu_torture_init() function's call to cpuhp_setup_state() fails, rcu_torture_cleanup() avoids invoking cpuhp_remove_state(). 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.
