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.

Paul, would you like to give some comments?
