//This routine empties the cancel safe queue and complete all the
// pended pre-read operations.
VOID PreReadEmptyQueueAndComplete(
    _In_ PINSTANCE_CONTEXT InstanceContext
    )

{
    NTSTATUS Status;
    FLT_PREOP_CALLBACK_STATUS callbackStatus;
    PFLT_CALLBACK_DATA Data;
    PQUEUE_CONTEXT QueueCtx;

    do {

        callbackStatus = FLT_PREOP_SUCCESS_NO_CALLBACK;

        Data = FltCbdqRemoveNextIo( &InstanceContext->Cbdq, NULL );

        if (Data) {

            QueueCtx = (PQUEUE_CONTEXT) Data->QueueContext[0];
            
		//changes here	
            if (!FlagOn(Data->Flags, FLTFL_CALLBACK_DATA_SYSTEM_BUFFER) && 
                Data->Iopb->Parameters.Read.MdlAddress == NULL &&
                Data->Iopb->Parameters.Read.Length > 0) {

                Status = FltLockUserBuffer( Data );

                if (!NT_SUCCESS( Status ))
		 {                   
                   
                    callbackStatus = FLT_PREOP_COMPLETE;
                    Data->IoStatus.Status = Status;
                }
            }

            FltCompletePendedPreOperation( Data,callbackStatus, NULL );

            ExFreeToNPagedLookasideList( &Globals.QueueContextLookaside,
                                         QueueCtx );
        }
