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
