Cpuset v2 has some useful behaviors that are not present in v1 because of backward compatibility concern. One of that is the restoration of the original cpu and memory node mask after a hot removal and addition event sequence. This patch makes the cpuset controller to check the CGRP_ROOT_CPUSET_V2_MODE flag and use the v2 behavior if it is set.

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.
