Hey Anton,

As discussed before (https://patchwork.ozlabs.org/patch/418583/), could you please
review the first five selftest test cases [patch 6, 7, 8, 9, 10] which are derived
from your DSCR test bucket and also consider acking them which will enable me to add
your Signed-off-by in the next version of the patch series. Thank you.
