This device will assist userspace to manage hotplug events. A userspace application reads a DeviceEvent entry until the return value is zero which indicates no events that are queued and waiting for processing. Trying to read with a buffer smaller than sizeof(DeviceEvent) results in EOVERFLOW. For now, there's no ioctl mechanism for this device but in the future an acknowledgement mechanism can be implemented via ioctl(2) interface.
