As far as it's not declared as a fix, I has no objection to this
patch.

Please always inline the patch in the mail body. And when resending
the patch, add the acked-by you collected in it:

Acked-by: Balbir ...
Acked-by: Paul ...
Signed-off-by: Xiaotian ...

You may resend the patch to Andrew Morton, who picks up cgroup
patches, otherwise the patch may be overlooked.
