Generally speaking I'd appreciate a usage example like here to the commit message: https://lwn.net/Articles/692514/ Is this doable? I might consider trying out the XFS test suite some day but right now it would be first nice to smoke test the feature quickly. I think for this patch that would actually be mostly sufficient testing. /Jarkko
