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.
