It makes a whole lot of sense, it just is a little harder to implement. There is no reason not to preallocate specific space, or if you aren't forced to be fully log structured by the medium, specific blocks to COW into. It just isn't quite as trivial as for a rewrite in place file system to implement. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
