Module irqfd 

Traits for irqfd-based interrupt delivery.

irqfd allows a hypervisor to directly inject an MSI into a guest when an event is signaled, without involving userspace in the interrupt delivery path. This is used for device passthrough (e.g., VFIO) where the physical device signals an event and the hypervisor injects the corresponding MSI into the guest VM.
