Comment 7 for bug 1014692

There is no cgroup supported with old kernel

ubuntu@c02:~$ cat /proc/version
Linux version 3.2.0-26-highbank (buildd@nihal) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #41-Ubuntu SMP PREEMPT Thu Jun 14 20:55:11 UTC 2012
ubuntu@c02:~$ cat /proc/filesystems | grep cgroup

and it looks good with new kernel

ubuntu@c02:~$ cat /proc/version
Linux version 3.2.0-27-highbank (buildd@ain) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #43-Ubuntu SMP PREEMPT Fri Jul 6 16:48:52 UTC 2012
