[snip test program]

Just a thought - can you write a set of tests using this (or
similar) test program and integrate them into xfstests?

That will help ensure correctness when implementing the API in other
filesystems (e.g. XFS ;), as well as provide some level of assurance
that we'll notice when we break the code...

Cheers,

Dave.
