My apologies if this is a newbie question. I'm still trying to figure out
the fine points of how MM works.
Why does read_swap_cache_async use GFP_USER as opposed to GFP_HIGHUSER for
swapped in pages? Is there some characteristic of reading swap pages that
doesn't allow use of highmem? Since anonymous pages can be allocated from
highmem, it seems to me it would make sense to also allow highmem pages
once they've been swapped out and back in.
