Indeed, sounds very interesting. However, from their github [1]:

> NOTE: The BetrFS prototype currently only works on the 3.11.10 kernel.

This is a tad limiting, hopefully they will port it to latest...

It's also currently stacked on top of ext4, and the tree data has to sit on some other filesystem as well. So promising design, but quite a long way from ready for production.

Not only that, but they need some fun patches...

> Our design minimizes changes to the kernel. The current code requires a few kernel patches, such as enabling direct I/O from one file system to another. We expect to eliminate most of these patches in future versions.

I prefer half-baked projects that are honest about their status over overpromised vaporware, personally
