Hmm, careful. There are a bunch of people who use suspend2 exactly because it saves and restores the page cache, leaving the system in a usable state without waiting for the universe to swap back in from disk. It makes a big difference on older laptops with slow drives. While the other advantages you list for process cryogenics are pretty neat, let's remember that the 99% use case for STD is laptops. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
