Can you please explain why you want to use XFS on low end, basic
non-MMU devices? XFS is a high performance, enterprise/HPC level
filesystem - it's not a filesystem designed for small IoT level
devices - so I'm struggling to see why we'd want to expend any
effort to make XFS work on such devices....

Cheers,

Dave.
