[求助]sfilter代码，在SfCleanupClose中加了一句调用SfDisplayCreateName，就蓝屏了

sfilter的其他代码都没用改动过，只在SfCleanupClose中函数中加了一句SfDisplayCreateFileName( Irp );  就蓝屏了。
下面是我的SfCleanupClose，大家请指教，帮一下新手吧。谢了

NTSTATUS  SfCleanupClose ( IN PDEVICE_OBJECT DeviceObject,   IN PIRP Irp )
{
   NTSTATUS status;
    PAGED_CODE();
    VALIDATE_IRQL(Irp);

    if (IS_MY_CONTROL_DEVICE_OBJECT(DeviceObject)) {

        Irp->IoStatus.Status = STATUS_SUCCESS;
        Irp->IoStatus.Information = 0;

        IoCompleteRequest( Irp, IO_NO_INCREMENT );
        return STATUS_SUCCESS;
    }

    ASSERT(IS_MY_DEVICE_OBJECT( DeviceObject ));

    SfDisplayCreateFileName( Irp ); //**********************这一句是我自己加的
    
    IoSkipCurrentIrpStackLocation( Irp );

    return IoCallDriver( ((PSFILTER_DEVICE_EXTENSION) DeviceObject->DeviceExtension)->AttachedToDeviceObject, Irp );
}

顶起来，继续求助

PAGE_FAULT_IN_NONPAGED_AREA (50)
Invalid system memory was referenced.  This cannot be protected by try-except,
it must be protected by a Probe.  Typically the address is just plain bad or it
is pointing at freed memory.
Arguments:
Arg1: bad0b148, memory referenced.
Arg2: 00000000, value 0 = read operation, 1 = write operation.
Arg3: 8092b6e2, If non-zero, the instruction address which referenced the bad memory
    address.
Arg4: 00000000, (reserved)

问题和lz的一样，求解释哈！！

应该是中断级问题！在dispatch级别上出现了缺页中断的访问！纯属个人意见！自己验证验证！
