>Adding a vfs call to check for file equivalence seems like a good idea to me. That would be only barely useful. It would let 'diff' say, "those are both the same file," but wouldn't be useful for something trying to duplicate a filesystem (e.g. a backup program). Such a program can't do the comparison between every possible pairing of file names. I'd rather just see a unique file identifier that's as big as it needs to be. And the more unique the better. (There are lots of degrees of uniqueness; unique as long as the files exist; as long as the filesystems are mounted, etc.). -- Bryan Henderson IBM Almaden Research Center San Jose CA Filesystems - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
