The problem is that patch 1/1 breaks the build. The rule is that we
should be able to apply part of a patch series and nothing breaks. If
we apply the patch series out of order than things break that's our
problem, yes. But if we apply only 1/1 and it breaks, that's a problem
with the series.

My other issue with this patch series which is related to #2 is that
it's not clear that anyone is checking the return value and doing
correct things with it.
Hopefully, when we use the attach_ret() approach then it will be more
clear if/how the return value is useful.
