Helpful macro would prove useful.
Yes, but the flip side is that people need to look at what the macro does to figure it out, while everyone knows what list_for_each_entry() means. Not sure about this one. And on top of this we'll probably have to rework this code to have a background copy of the current bank in the alternate bank so it'd rather leave it simple for now.
