In support of Cache Pseudo-Locking we need to restrict access to specific resctrl files to protect the state of a resource group used for pseudo-locking from being changed in unsupported ways. Introduce two utilities that can be used to either restrict or restore the access to all files irrelevant to cache pseudo-locking when pseudo-locking in progress for the resource group. At this time introduce a new source file, intel_rdt_pseudo_lock.c, that will contain most of the code related to cache pseudo-locking. Temporarily mark these new functions as unused to silence compile warnings until they are 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.
