Looks like you can do better without even patching the kernel:

Yup, trying it on Slackware 64 13.0, but /sys/fs/cgroup/ is empty and i can't create cpu directory.
I compiled all cgroup options in the kernel.

Any idea ?

Hi Linux.tar.gz,

Just recompiled the 2.6.37-rc2 kernel adding the cgroup stuff and faced the same behavior: No /sys/fs/cgroup/cpu is created.
Anyway since I don't have time right now to search further, tried the "ubuntu" way (use /dev instead of /sys/fs) and it works (tasks are created under /dev/cgroup/cpu/user/xxx), even though I didn't see any noticeable difference than before.
Hopefully I could do some tests during the weekend

Regards

Used the "Fedora" way http://forums.fedoraforum.org/showthread.php?p=1418113, and it (seems to) works too, but like you, there's absolutely no difference...
As said in other thread, seems there's a service to start ...

It works !!!

Just remember to CLOSE the terminal when testing, because it keeps the .bashrc settings, even if you modify it (of course)!
