Hi all, This is just something I slapped together when poking around and learning the reflink cow fork stuff. E.g., I find it useful to see exactly what's going on in certain situations, verify the background reclaim works, etc. I'm not sure it's worthy of a generic fiemap flag since I believe the cow fork is a fairly XFS-specific mechanism, it's limited to extra blocks that haven't been written, and probably dumps information obtainable via other means (tracepoints). I'm throwing it up on the list anyways for reference and/or archival purposes, if nothing else. Thanks!
