Hi Hugh,

Thanks a lot for checking and patch. I am in traveling today. So
just can pick and put it as lruv21 branch on my github tree:
https://github.com/alexshi/linux.git

Hi Rong,

We will very appreciate if you could launch testing on the branch
and it'd better, if you have time to change the test case time as 1k
second as Hugh wanted. Many thanks!

Thanks
Alex
