Now I'm confused. How do you do usefull resume from disk when you > don't restore complete state? Do you propose something like "write > only pagecache to disk"? Go back to the original _reason_ for this whole discussion. It's not really a "resume" event, it's a "populate caches really efficiently at boot" event. But the two are basically the same problem, it's only a matter of how much you populate (do you populate _everything_ or do you populate just disk caches. Populating just the caches is the smaller and simpler problem, that only solves the "fast boot" issue). Linus
