I don't still comprehend the need for a library on top of dmaengine which gain is just a library between clients and dmacs. Surely we don't want to write another abstraction on top of one provided? If the question is to handle scatter-gather even if the hardware doesn't have the capability, then why don't add that in dmaengine itself rather than one more layer? -- ~Vinod -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
