Several patches in this series are clearly bug fixes that should come first in
the series and have a fixes tag and cc-stable. Can you please reorganize the
series with the fixes first ?

Also please try to avoid growing the patch series with more patches in response
to sachiko "not introduced by this patch" comments on valid problems. Send
incremental patches instead. Otherwise, making progress will take a longer time,
and bigger series are harder to review.
