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.
