Each RDT resource group is associated with a mode that will reflect the level of sharing of its allocations. The default, shareable, will be associated with each resource group on creation since it is zero and resource groups are created with kzalloc. The managing of the mode of a resource group will follow. The default resource group always remain though so ensure that it is reset to the default mode when the resctrl filesystem is unmounted. Also introduce a utility that can be used to determine the mode of a resource group when it is searched for based on its class of service.

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.
