I'm not going to rush the incremental patch to fix this: need to think about it quietly first. If you're wondering what I'm talking about (sorry, I don't have time to explain more right now), take a look at comment and git history of line 2956 (in 3.4-rc7) of mm/memory.c: if (unlikely(!PageSwapCache(page) || page_private(page) != entry.val)) I don't suppose anyone ever actually hit the bug in the years before we added that protection, but we still ought to guard against it, there and here in shmem_replace_page().
