The thing I'd like to see is: - a more recent description of file system layout I've read the original paper, and I assume things have changed when implementing stuff. They always do. - some benchmarks and/or comments about regular usage (ie fragmentation etc). Yeah, it doesn't need to be all that extensive, but quite frankly, it sounds like this is meant to be at least a partial replacement for a GP filesystem (considering that seek/rotational delay are going away) and people are working on it with USB memory sticks etc, wouldn't it make sense to talk about disk usage (how much the GC wants free etc) and everyday performance? Hmm? Linus
