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.

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.
