Is that means:
you have already tested the Linux branch which contains the commit
fd74da217df7d. and it doesn't work well.
Btw, Why the test is incomplete run ?
> The bug still persists in v4.9, v4.10-rcx, the lastest kernel head,
If the dmesg and stat of the test is NULL, How do you prove that the
bug still exists?

Yes, I think we first should make the test with commit fd74da217df7d
work in the specific test machine.
test machine: 72 threads Intel(R) Xeon(R) CPU E5-2699 v3 @ 2.30GHz with

Am I right? waiting your response.
