During CAT feature discovery the capacity bitmasks (CBMs) associated with all the classes of service are initialized to all ones, even if the class of service is not in use. Introduce a test that can be used to determine if a class of service is in use. This test enables code interested in parsing the CBMs to know if its values are meaningful or can be ignored. Temporarily mark the function as unused to silence compile warnings until it is used.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
