It is looking at the current free page levels, on a zone-by-zone
basis. Looking at the return value of try_to_free_pages() doesn't
make much sense IMHO because that just means that normal processes
will be doing the heavy work instead of kswapd (leading to poor
interactive response and other trouble).
