I tried checking this, struct sh_desc have moved to struct shdma_desc in shdma-base.h. But the field partial was dropped, so we need to use residue here. But, shdma or base doesn't calculate residue for err transactions, so you cannot use it to start a new one. -- ~Vinod -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
