Dpage_owner.rst11 page owner: 跟踪谁分配的每个页面
17 page owner是用来追踪谁分配的每一个页面。它可以用来调试内存泄漏或找到内存占用者。
27 统计。如果启用了page owner，它就已经实现并激活了。我们非常欢迎其他用途。
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 - 没有page owner::
42 - 有page owner::
50 中。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最佳选择。
68 2) 启用page owner: 添加 "page_owner=on" 到 boot cmdline.
