Opening this question to a wider audience.
struct scatterlist gives us struct page*, and an offset+length pair.
The struct page* is the _starting_ page of a potentially multi-page run
of data.
The question: how does one get struct page* for the second, and
successive pages in a known-contiguous multi-page run, if one only knows
the first page?
