The layout is most likely going to be different anyway, isn't it? We don't know what has gone on in the past to get the FS into the current state. But now we have more information than we did when the file system was originally built. We don't have an extent based interface do we? So we can't say "I know this file is going to be X bytes in size." But if we accomplish nearly the same thing by a quick copy like this, what's the harm? mrc -- Mike Castle dalgoda@ix.netcom.com www.netcom.com/~dalgoda/ We are all of us living in the shadow of Manhattan. -- Watchmen fatal ("You are in a maze of twisty compiler features, all different"); -- gcc - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
