在HOOK中如何同步

比如我HOOK了某个driver的IRP_MJ_CREATE,在我的例程中如何做到象下列一样的同步:
    KeInitializeEvent(&Event, NotificationEvent, FALSE);
    IoCopyCurrentIrpStackLocationToNext(Irp);
    IoSetCompletionRoutine(Irp, SyncronouslyCompletion, &Event, TRUE, TRUE, TRUE);
    Status = IoCallDriver(DeviceObject, Irp);
    if (STATUS_PENDING == Status)
    {
        KeWaitForSingleObject(&Event, Executive, KernelMode, FALSE, NULL);
        Status = Irp->IoStatus.Status;
    }
    return Status;
