An active boolean is introduced on producer side: it reflects whether the source is active (at interrupt controller level or at VFIO level - automasked -). This is a temporary hack for ARM IRQ forwarding with vfio platform. I think the connect and disconnect should become callbacks too. This would make possible to handle error in the process. Typically active could be returned by producer->stop and analyzed before going further. in that case the list_add only if connect returns 0.
