From: Shuang Qiu <shuang.qiu@oracle.com>

As the legacy of:
  commit 8793d854edbc2774943a4b0de3304dc73991159a
  Author: Paul Menage <menage@google.com>
  Date:   Thu Oct 18 23:39:39 2007 -0700
  Task Control Groups: make cpusets a client of cgroups
there is no cpuset. prefix for cpuset subsystem if ever mount it as cpuset type.
So try either $mount_point/XXXX or $mount_point/cpuset.XXXX.
