RE: [PATCH 3/4] Extend the DMA-engine API.

["Zhang Wei-r63237" <Wei.Zhang@freescale.com>]

Hi, Dan, 

Do you mention here: http://marc.info/?l=linux-raid&m=118290909614463&w=2 ?
I see the async_tx is located at crypto/ of the above page, but my patch is for DMA engine in drivers/dma and for DMA engine driver.

Thanks!
Wei.
