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
