I would be happy to extend swap prefetch's capabilities to improve resume. It wouldn't be too hard to add a special post_resume_swap_prefetch() which aggressively prefetches for a while. Excuse my ignorance, though, as I know little about swsusp. Are there pages still on swap space after a resume cycle?
