Pool资源释放

黑夜愁客 2010-01-25 05:48:51

我在Filter种Attach的时候，分配了一个Pool:

NdisZeroMemory(&PoolParameters, sizeof(NET_BUFFER_LIST_POOL_PARAMETERS));



        PoolParameters.Header.Type = NDIS_OBJECT_TYPE_DEFAULT;

        PoolParameters.Header.Revision = NET_BUFFER_LIST_POOL_PARAMETERS_REVISION_1;

        PoolParameters.Header.Size = sizeof(PoolParameters);

        PoolParameters.ProtocolId = NDIS_PROTOCOL_ID_DEFAULT ;

        PoolParameters.ContextSize = sizeof(FILTER_SEND_NETBUFLIST_RSVD);

        PoolParameters.fAllocateNetBuffer = TRUE;

        PoolParameters.PoolTag = FILTER_ALLOC_TAG;

        

        pFilter->SendNetBufferListPool = NdisAllocateNetBufferListPool(

                                                    NdisFilterHandle,

                                                    &PoolParameters); 

        if (pFilter->SendNetBufferListPool != NULL)

         {

            DEBUGP(DL_TEST, ("FileAttach: Successfully to alloc send net buffer list pool\n"));

         }else{

		    DEBUGP(DL_TEST, ("FileAttach: failed to alloc send net buffer list pool\n"));

            Status = NDIS_STATUS_RESOURCES;

            break;

        }

中间会有用到SendNetBufferListPool，来分配一个NBL.
然后想在FilterDetach的时候释放pool

    if(pFilter->SendNetBufferListPool !=NULL)

	{

	    NdisFreeNetBufferPool(pFilter->SendNetBufferListPool);

		pFilter->SendNetBufferListPool = NULL;

	}

结果执行到这里的时候：

能看到这些调试信息吗，IRQL 怎么会抬高呢，NDIS 调用FilterDetach是以PASSIVE_LEVEL的？到了释放pool就不行了？
谢谢
