Maybe the code handles that by making sure that all the pages in the range

It doesn't, I'm assuming that find_get_pages() returns consequtive pages
atm. Would seem like the sane interface :-)
It doesn't.
You could do a find_get_pages_and_holes (or something along those
lines), which would fetch contiguous pagecache and stick NULLs
if pages don't exist.
Would require a bit of radix-tree support to do it nicely, but you
could get started with a naive find_get_page loop.
