As an extra request, it would be great if people explained a little
about their use-case for the filesystem so we can better understand
how the features requested map to the type of workloads people are
trying.

Thanks

(This isn't to say that the base feature set is stable now, but it's much closer than when you turn on some of the other things.) I'd like to get feedback from you in the community on what minimum supported feature set would prompt or allow you to start using CephFS in real environments — not what you'd *like* to see, but what you *need* to see. This will allow us at Inktank to prioritize more effectively and hopefully get out a supported release much more quickly! :)
