Looks like only works with Linux kernel - 3.11? https://github.com/oscarlab/betrfs/blob/master/README.md , so definitely have not been updated for awhile.

I am not even sure it wants to be production ready but may be it is a playground for ideas.

Indeed, we are behind on releases. We do anticipate a major release, including 4.19 kernel support, in the coming months.

Part of our challenge is that we are also exploring non-standard extensions to the VFS API - largely supported by kallsyms + copied code to avoid kernel modifications. This makes rolling forward more labor intensive, but we are working to pay down this technical debt over time, or possibly make a broader case for a VFS API change.

Extricating something from specific kernel API calls won't be fun. Might be a good learning experience, tho. I may take a crack at this in my spare time (I'm not good at C. At all. So this will be more learning for me, and much less functional).
