Right now, my main priority is stabilizing it and making it usable - fixing all the things that people are going to trip over when they try it out. I want to get it somewhat more polished before I announce on linux-fsdevel. The big thing I'm working on at the moment is debugging atomic renames, I had to back that code out at the last minute. > I'd like to pick something to work on. Probably the debugfs tool you > mentioned or other things? One thing that would actually be really helpful is more benchmarking vs. ext4/xfs - identifying areas where there's still more performance work to do. The debugfs tool is definitely important but that's a longer term thing. If you're feeling productive like that feel free to keep going with it. Really though right now the main thing we need is more testing and debugging.
