>> Brtfs wiki describes a method to convert an ext4 filesystem to btrfs without data loss

The tool uses a userspace library to read the filesystem and setup Btrfs. Adding support for XFS (or any other fs) should mostly involve getting a user space library to read XFS and calling the appropriate functions from the conversion tool to setup Btrfs.
