If we want to have more coverage, how about importing the lz4demo utility source code to tools/lz4/, and change scripts/Makefile.lib to point at it? Once the lz4 utilities have reached a broader audience and are available with most distributions, we could revert back to assuming this utility can be found in PATH. -- Florian -- 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/
