Don't worry too much about it, indeed; though I agree it'd be much
nicer tucked away somewhere else, near read_swap_cache_async or
near valid_swaphandles or the three brought together.
(But if you do want to worry about swapin_readahead, just savour the
absurdity of its NUMA next_vma code: just what is the likelihood that
swap allocation will match a task's address layout?)
