Jacek, as resending an updated version of this patch with Joe's suggestions taken into account would be even more confusing than the "PATCH v2 6+/6" subject I already resorted to, I suggest the following: if this series goes to v3, I will include an updated version of this patch in v3, but in case the remaining patches get acked in their current shape by all maintainers, I will send an updated version of this extra patch separately, after the rest of the series gets applied. Does this sound reasonable?
