Waiman Long 49277a5b76 workqueue: Move workqueue_set_unbound_cpumask() and its helpers inside CONFIG_SYSFS 
Commit fe28f631fa ("workqueue: Add workqueue_unbound_exclude_cpumask()
to exclude CPUs from wq_unbound_cpumask") makes
workqueue_set_unbound_cpumask() static as it is not used elsewhere in
the kernel. However, this triggers a kernel test robot warning about
'workqueue_set_unbound_cpumask' defined but not used when CONFIG_SYS
isn't defined. It happens that workqueue_set_unbound_cpumask() is only
called when CONFIG_SYS is defined.

Move workqueue_set_unbound_cpumask() and its helpers inside the
CONFIG_SYSFS compilation block to avoid the warning. There is no
functional change.

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.
