It is new. And yes we will have proper support for sccatterlists. We need something similar to what sg and st need so I plan on using the block layer functions that are implemented for those upper layer drivers for stgt. If you want to help out and implement that then that would be good. We are also very early in our design so all comments are welcome. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
