[PATCH 00/12] Resource Groups... formerly CKRM

[Chandra Seetharaman]

Andrew,

CKRM has gone through a major overhaul by removing some of the complexity,
cutting down on features and moving portions to userspace.

We have posted ckrm last week as an RFC:
infrastructure:
	http://www.ussg.iu.edu/hypermail/linux/kernel/0604.2/1297.html
numtasks controller:
	http://www.ussg.iu.edu/hypermail/linux/kernel/0604.2/1311.html
CPU controller:
	http://www.ussg.iu.edu/hypermail/linux/kernel/0604.2/1310.html

Diffstat of this patchset (including the numtasks controller that follows)
is:

	23 files changed, 2466 insertions(+), 5 deletions(-)

including Documentaion and comments.

This patchset will be followed with two controllers:
	- a simple controller, numtasks to control number of tasks
	- CPU controller, to control CPU resource.

Please consider these for inclusion in -mm tree.

Changes since last post:
 - CKRM has been replaced with Resource Groups
 - 'class' has been replaced with resource group
 - Limit the depth of the hierarchy.
