I prefer the same order as they appear in the .config file. Like this. +# CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE is not set CONFIG_CC_OPTIMIZE_FOR_SIZE=y +# CONFIG_KERNEL_GZIP is not set +# CONFIG_KERNEL_BZIP2 is not set +# CONFIG_KERNEL_LZMA is not set CONFIG_KERNEL_XZ=y +# CONFIG_KERNEL_LZO is not set +# CONFIG_KERNEL_LZ4 is not set CONFIG_OPTIMIZE_INLINING=y +# CONFIG_SLAB is not set +# CONFIG_SLUB is not set CONFIG_SLOB=y -- Best Regards Masahiro Yamada -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
