-# Exporting kernel headers for use by userspace
 
-The \"make headers_install\" command exports the kernel\'s header files
-in a form suitable for use by userspace programs.
+# 导出内核头文件供用户空间使用
 
-The linux kernel\'s exported header files describe the API for user
-space programs attempting to use kernel services. These kernel header
-files are used by the system\'s C library (such as glibc or uClibc) to
-define available system calls, as well as constants and structures to be
-used with these system calls. The C library\'s header files include the
-kernel header files from the \"linux\" subdirectory. The system\'s libc
-headers are usually installed at the default location /usr/include and
-the kernel headers in subdirectories under that (most notably
-/usr/include/linux and /usr/include/asm).
+"make headers_install" 命令以适合用户空间程序使用的形式导出内核的头文件。
 
-Kernel headers are backwards compatible, but not forwards compatible.
-This means that a program built against a C library using older kernel
-headers should run on a newer kernel (although it may not have access to
-new features), but a program built against newer kernel headers may not
-work on an older kernel.
+Linux 内核导出的头文件描述了用户空间程序尝试使用内核服务的 API。这些内核头文件被系统的 C 库（例如 glibc 和 uClibc）用于定义可用的系统调用，以及与这些系统调用一起使用的常量和结构。C 库的头文件包括来自 "linux" 子目录的内核头文件。系统的 libc 头文件通常被安装在默认位置 /usr/include，而内核头文件则在该位置的子目录下（尤其是 /usr/include/linux 和 /usr/include/asm）。
 
-The \"make headers_install\" command can be run in the top level
-directory of the kernel source code (or using a standard out-of-tree
-build). It takes two optional arguments:
+内核头文件向后兼容，但不向前兼容。这意味着使用旧内核头文件和C库构建的程序可以在新内核上运行（尽管它可能无法访问新功能），但使用新内核头文件构建的程序可能无法在旧内核上运行。
+
+"make headers_install" 命令可以在内核源代码的顶层目录中运行（或使用标准的树外构建）。它接受两个可选参数：
 
     make headers_install ARCH=i386 INSTALL_HDR_PATH=/usr
 
-ARCH indicates which architecture to produce headers for, and defaults
-to the current architecture. The linux/asm directory of the exported
-kernel headers is platform-specific, to see a complete list of supported
-architectures use the command:
+ARCH 指示为其生成头文件的架构，默认为当前架构。导出内核头文件的 linux/asm 目录是基于特定平台的，要查看支持架构的完整列表，使用以下命令：
 
     ls -d include/asm-* | sed 's/.*-//'
 
-INSTALL_HDR_PATH indicates where to install the headers. It defaults to
-\"./usr\".
+INSTALL_HDR_PATH 指示要安装头文件的位置。默认为 "./usr"。
+
+一个 'include' 目录会自动被创建在 INSTALL_HDR_PATH 中，头文件会被安装在 INSTALL_HDR_PATH/include 中。
 
-An \'include\' directory is automatically created inside
-INSTALL_HDR_PATH and headers are installed in
-\'INSTALL_HDR_PATH/include\'.
