Peter: copy changlong's testing result again, the ltp cgroup stress testing show this patchset can reduce the stress testing time: # run test 7. sudo ./runltp -p -l /tmp/cgroup.results.log -d /tmp -o /tmp/cgroup.log -f cgroup my test results: 3.10-rc1 patch1-7 patch1-8 duration=764 duration=754 duration=750 duration=764 duration=754 duration=751 duration=763 duration=755 duration=751 duration means the seconds of testing cost.
