Dan,
I just noticed that your patch "dmaengine: add the async_tx api":
@@ -22,6 +22,17 @@ config NET_DMA
Since this is the main user of the DMA engine, it should be enabled;
say Y here.
+config ASYNC_TX_DMA
+ tristate "Asynchronous Bulk Memory Transfers/Transforms API"
+ default y
+ ---help---
+ This enables the async_tx management layer for dma engines.
+ Subsystems coded to this API will use offload engines for bulk
+ memory operations where present. Software implementations are
+ called when a dma engine is not present or fails to allocate
+ memory to carry out the transaction.
+ Current subsystems ported to async_tx: MD_RAID4,5
+
adds ASYNC_TX_DMA unconditionally to _all_ platforms. You might what to bundle
this with something like DMA_ENGINE.
Best regards,
Stefan
