    Exciting ;) It's much less code than I expected.

    I don't think I understand the feature any more. Once upon a time we
    thought that this might become a new and better (or at least
    better-code-sharing) way of doing suspend-to-disk. How far are we from
    that?

    What are the prospects of supporting other architectures?

    Who maintains kexec-tools, and are they OK with merging up the
    corresponding changes?

    Thanks.
