This does not seem like a good solution for two reasons. The first is
that LTP should be backward compatible with older distributions and the
second is that the testcase umounts and removes the directory at the end
of the test which will break the system since the /sys/fs/cgroup/cpuset
directory is mounted (and possibly used) by default on newer
distributions.

So the test should be changed to:

* Create and mount cpuset on older distros

* Make use of allready moutned cpuset on newer distros

The cgroup_fj/cgroup_fj_common.sh was allready fixed to work this way.
