These tests all failed in the same way like:

    +scrub didn't fail with diskdq.magic = zeroes.
    +scrub didn't fail with diskdq.magic = ones.
    +scrub didn't fail with diskdq.magic = firstbit.
    +scrub didn't fail with diskdq.magic = middlebit.
    ...

with 4.13-rc5 kernel and xfsprogs for-next branch. I assume that's
something need to be fixed in the kernel?

Yes, that's testing whether or not online scrub actually notices when
we corrupt something.  I'll look into it, but output like that is a sign
that the test is working as designed. :)
