BTW,
for 4.15 kernel on a KVM node, although it's showing "ERROR: incorrect queue
lengths" all the time, the test result is not very consistent, sometimes it
passes and sometimes it failed (33 failures out for 100 attempts)
The upstream code has also changed this ERROR to warning, we can use
that to reduce confusion.
