Hi @jamespharaoh I'm currently getting the above error when trying to build. Any ideas?

A friend of mine fixed it here https://github.com/pluth/btrfs-dedupe. But it'll run into other problems if you run any kind of recent kernel because Btrfs behaviour has changed.

Perhaps someone with access to this wiki: https://btrfs.wiki.kernel.org/index.php/Deduplication Sould remove it then or put BOLD warnings on what version it is compatible with before they destroy their data!
