最后1GB用于内核数据结构。
注意：本文涉及到的内核数据结构和文件名是当前Linux版本中所使用的。
Note: The kernel data structures and file names referred to in this article are those used in current Linux versions.
类似地，同样可以无干扰地记录Linux内核数据结构的日志，甚至进行修改。
Similarly, Linux kernel data structures can also be logged and even modified non-disruptively, as well.
如果用于内核的库子程序和数据结构的定义有变化，而且这种增进不再编译，那就要注意并加以修补。
If the definition of library routines and data structures used in the kernel are changed and the enhancements no longer compile this will be noticed and repaired.
正如您可能猜到的那样，内核和内部数据结构也需要进行修改来支持这种虚拟化方法。
As you can guess, the kernel and internal data structures are modified to support this approach to virtualization.
真实的情况是，SAP系统拥有一个附带业务流程特定数据结构（业务对象）的通用内核并在其上处理逻辑。
Under the covers, an SAP system has a common kernel plus business process specific data structures (business objects) and processing logic on top of it.
这个数据结构是一个“红-黑”树，对于注重性能的应用程序很理想(且恰好作为内核中的一个库普遍可用)。
The data structure used is a red-black tree, which is ideal for performance-focused applications (and happens to be available generically as a library within the kernel).
Linux内核调试器(Linux kernel debugger,kdb)是Linux内核的补丁，它提供了一种在系统能运行时对内核内存和数据结构进行检查的办法。
The Linux kernel debugger (KDB) is a patch for the Linux kernel and provides a means of examining kernel memory and data structures while the system is operational.
简介：调试内核问题时，能够跟踪内核执行情况并查看其内存和数据结构是非常有用的。
Summary: When debugging kernel problems, being able to trace the kernel execution and examine its memory and data structures is very useful.
这个恰如其名的工具实质上是内核代码的补丁，它允许高手访问内核内存和数据结构。
This aptly named tool is essentially a patch to the kernel code that lets hackers access kernel memory and data structures.
这些数据结构用于为传入的和出站的流量存储内核数据。
These are used to store kernel data for incoming and outbound traffic.
因此，内核会无法找到它，并将从它的链表尾部离开，导致了破坏了进程中的那些数据结构。
Therefore, the kernel will fail to find it, and will walk off the end of its lists, corrupting those data structures in the process.
在驱动的私有数据结构中，驱动程序保存了所有的用于驱动设备的必要信息以及与内核交互时必须的组件信息。
The driver stores, in private data structures, all the information needed to drive the device and interact with other kernel components that require the device.
您可以使用drbdsetup 在Linux内核中配置DRBD 模快，使用drbdmeta管理 DRBD 元数据结构。
You use the drbdsetup utility to configure the DRBD module in the Linux kernel and drbdmeta to manage DRBD's metadata structures.
很快你就能看到，你可以通过操作不同的内核队列数据结构来改变内核对操作系统状态的感知。
As you'll soon see, you can alter how the kernel perceives the operating system's state by manipulating the various kernel queue data structures.
第15章，《网卡驱动》，分析了网络设备驱动，您将学习到内核中与网络相关的数据结构以及网络设备驱动与协议栈接口的方法。
Chapter 15, "network interface Cards", is devoted to network device drivers. You will learn about kernel networking data structures and how to interface network drivers with protocol layers.
在内核中，普通进程有若干数据结构与之关联，包括一个堆栈，进程控制块(PCB)。
A normal process has a number of data structures associated with it in the kernel, including a stack and process control block (PCB).
到目前为止，我已经把所有内核进行内存管理的重要的数据结构介绍了一遍，接下来，我们就可以用前面所讲的知识来对目标计算机进行物理内存镜像的分析了。
I have already described important structures of the kernel memory, so now we can use this knowledge to find evidence in the physical memory of the compromised machine.
这些数据结构里面的大部分都是当你首次创建线程或者进程的时候被创建和初始化的，它们所需的代价成本很高，因为需要和内核交互。
The space for this memory is set aside in your process space at thread creation time, but the actual pages associated with that memory are not created until they are needed.
