I think read_swap_page_async should be acting as a lookup on the page
cache, so the page it returns is guaranteed to have an incremented
reference count. You'll need to free_page() it just after the
read_swap_page_async() call to get the expected behaviour.
You still need to skip locked swap entries, too.
