Introduce generic structures and routines for resource accounting.
Each resource accounting container is supposed to aggregate it,
container_subsystem_state and its resource-specific members within.

Choose if we want cached pages to be accounted or not. By default both

Here's a tentative development plan on resource management from our side.
Would request others to comment/add their plans as part of this discussion.
This plan, alongwith appropriate usage scenarios, is being requested for
kernel-summit discussion. Most likely, the resource management plans

This example demonstrates how to use the generic container subsystem for a
simple resource tracker that counts, for the processes in a container, the
total CPU time used and the %CPU used in the last complete 10 second interval.

This patch adds support for container_clone(), a way to create new
containers intended to be used for systems such as namespace
unsharing. A new subsystem callback, post_clone(), is added to allow
subsystems to automatically configure cloned containers.

This patch replaces the struct css_group embedded in task_struct with a
pointer; all tasks that have the same set of memberships across all
hierarchies will share a css_group object, and will be linked via their
css_groups field to the tasks list_head in the css_group.
