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?

                    ^^^^ I changed it to 1382 then renumbered.
