I haven't tried 2.6.38 yet but I'm one of the authors of http://en.gentoo-wiki.com/wiki/Improve_responsiveness_with_cgroups I guess you can follow that guide (except that step about adding lines to ~/.bashrc which is supposedly obsolete in 2.6.38). Then you can see for yourself how the kernel arranges your processes in cgroups. Your cgroup mount point should contain directories (different groups) and in each directory there is a "tasks" file containing process ids of the associated tasks. While you are at it, you could update the information on the wiki. Any help there is appreciated. :) Regards, Florian Philipp
