I've read the patches a few times and still can't see how the meaning of
'cancelled' fits. It's about cancelling write out yes, but I don't see
anywhere explained why and why the eb is zeroed. This could be put next
to the enum definition or to function that does the main part of the
logic. You can also rename it to CANCELLED_WRITEOUT or use _ZONED_ in
the name so it's clear that it has a special purpose etc, but as it is
now I think it should be improved.
