from a pool before you destroy the pool. This function may not

+Some architectures which supporting DMA coherent memory may still have write
+buffering between the CPU and DMA memory. This buffering may delay CPU writes
+from reaching coherent memory in a timely manner. These delays in turn can
+lead lead to dramatic performance issues in certain cases. An architecture
+may mitigate this problem to a large degree by having a write buffer flush
+implicit in the MMIO functions used to write to device registers. This works
+for the most common cases where a driver needs to write to a register to tell
+a device that something was written to the shared coherent memory. There are
+other cases where the device polls the dma-coherent memory for data written
+by the driver. In such cases, the driver needs to explicity force write buffer
+data to memory by calling:
