Yes I know. I thought some XFS dev might contact the Author to do some 
re-testing, as a reputation is quickly destroyed by such articles and 
takes long to be returned. Just this week I had a friend in a FS 
discussion saying "ins't XFS destroying/zeroing files on power 
failure?". That information is ancient, but things like that stay in 
peoples brain for(almost)ever.
