When doing cpuset_hotplug test, it will mount cpuset filesystem on
/dev/cpuset and try to 'cat' cpuset.cpus file. But the cpuset.cpus
doesn't exist because the cgroup system generates cpus without 'cpuset'
prefix instead. The result is undoubtly TFAIL.
The old ltp test uses "mount -t cpuset cpuset "$CPUSET"" which will
mount with 'noprefix' options in the kernel(see kernel/cgroup/cpuset.c).
The reason is that it wants the backwards compatibility for the old
cpuset file system. Therefore, using "mount -t cgroup -o" method
surely fixes this issue once for all.

Hi Jason,
It looks good to me. :-)

Hi Yang,
Thanks for your review.
But it seems that the maintainers miss this patch, it's not a
complicated one, just one line changed. So I decided to reply to you all.
