We discussed the naming problem before, one big problem is that the 'segment'
in bio_for_each_segment*() means one single page segment actually.

If we use segment_iter_page() here for multi-page segment, it may
confuse people.

Of course, I prefer to the naming of segment/page,

And Jens didn't agree to rename bio_for_each_segment*() before.

So what is the solution we should take for moving on?

OK.
