Add monitoring support during mount and unmount. Since root directory is a "ctrl_mon" directory which can control and monitor resources create the "mon_groups" directory which can hold monitor groups and a "mon_data" directory which would hold all monitoring data like the rest of resource groups. The mount succeeds if either of monitoring or control/allocation is enabled. If only monitoring is enabled user can still create monitor groups under the "/sys/fs/resctrl/mon_groups/" and any mkdir under root would fail. If only control/allocation is enabled all of the monitoring related directories/files would not exist and resctrl would work in legacy mode.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
