Please don't introduce new DMA_ATTR_NON_CONSISTENT users, it is a rather horrible interface, and I plan to kill it off rather sooner than later. I plan to post some patches for a better interface that can reuse the normal dma_sync_single_* interfaces for ownership transfers. I can happily include usb in that initial patch set based on your work here if that helps.
