29 page owner在默认情况下是禁用的。所以，如果你想使用它，你需要在你的启动cmdline
30 中加入"page_owner=on"。如果内核是用page owner构建的，并且由于没有启用启动
31 选项而在运行时禁用page owner，那么运行时的开销是很小的。如果在运行时禁用，它不
37 尽管启用page owner会使内核的大小增加几千字节，但这些代码大部分都在页面分配器和
38 热路径之外。构建带有page owner的内核，并在需要时打开它，将是调试内核内存问题的
57 2) 启用page owner: 添加 "page_owner=on" 到 boot cmdline.
