I tried to look at it and it surely looks very temping and may fit
well and reduce size of my backend :)
I am now wondering how interrupts can be made to work here. Do you
have anything in mind for that ?
GPIO sysfs already supports interrupts, just that you need to register
irq for the specific GPIO pins inside the aggregator ?
