That sounds reasonable to me. Those could be pretty trivial wrappers.
- rename nents and orig_nents to nr_pages, nr_dmas to clearly state which one refers to which part of the scatterlist; I'm open for other names for those entries
nr_cpu_ents and nr_dma_ents might be better names, but it still would be a whole lot of churn for little gain. I think just good wrappers like suggested above might be more helpful.
