Hi, kernel test robot

Please help to make tests with the following commits.

Please let us know the result.
I don't think that the kernel test robot understands the above request.
Got it. I do not know how to let test robot make tests with this patch.^_^
we can test the patch for you. just cannot test quickly due to resource
constraint. will let you know the results in one or two days. thanks
the WARNING is random in our tests. for aee2424246, it shows up 6 times in 20
runs as below table.

the "e0cc1e2cd74a66b5252ea674a26" is just your fix patch.

we run it to 100 times, and the issue doesn't show.

Tested-by: kernel test robot <oliver.sang@xxxxxxxxx>

Thanks a lot for your tests. I will send out the latest patch very soon.

Zhu Yanjun
