The ww-mutex selftest operates directly on ww_mutex::base and assumes its type is struct mutex. This isn't true on PREEMPT_RT which turns the mutex into a rtmutex. Add a ww_mutex_base_ abstraction which maps to the relevant mutex_ or rt_mutex_ function. Change the CONFIG_DEBUG_MUTEXES ifdef to DEBUG_WW_MUTEXES. The latter is true for the MUTEX and RTMUTEX implementation of WW-MUTEX. The assignment is required in order to pass the tests.

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.
