Ok, I agree. A flag is not optimal. I did some reading but I think you cant tell if a file system has that issue. I slightly more elaborate approach than just checking for file size 0 (as Jim did) would be to actually try to read such a file and see if you can get anything from it. If yes, than diff by looking into the content. However, still procfs or worse debugfs could report anything as size. The only proper fix would be to ignore file sizes entirely. ~stephan
