The callback routine flushes any data remaining in the memory region described by an MDL.
A pointer to a DMA_ADAPTER structure. This structure is the adapter object that represents the driver's bus-master DMA device or system DMA channel. The caller obtained this pointer from a previous call to the IoGetDmaAdapter routine.
A pointer to the MDL that describes the buffer previously passed in the driver's call to MapTransfer.
Specifies TRUE if the flush is being performed for a read operation, and FALSE for a write operation. For more information, see the following Remarks section.
Returns STATUS_SUCCESS if the call is successful. Otherwise, returns an appropriate NTSTATUS values error code. For more information, see NTSTATUS Values.
