+Each mount of the devpts filesystem is now distinct such that ptys

-To support containers, we now allow multiple instances of devpts filesystem,
-such that indices of ptys allocated in one instance are independent of indices
-allocated in other instances of devpts.
+All mounts of the devpts filesystem now create a /dev/pts/ptmx node
+with permissions 0000.
 
-To preserve backward compatibility, this support for multiple instances is
-enabled only if:
+To retain backwards compatibility the a ptmx device node (aka any node
+created with "mknod name c 5 2") when opened will look for an instance
+of devpts under the name "pts" in the same directory as the ptmx device
+node.
 
-	- CONFIG_DEVPTS_MULTIPLE_INSTANCES=y, and
-	- '-o newinstance' mount option is specified while mounting devpts
-
-IOW, devpts now supports both single-instance and multi-instance semantics.
-
-If CONFIG_DEVPTS_MULTIPLE_INSTANCES=n, there is no change in behavior and
-this referred to as the "legacy" mode. In this mode, the new mount options
-(-o newinstance and -o ptmxmode) will be ignored with a 'bogus option' message
-on console.
-
-If CONFIG_DEVPTS_MULTIPLE_INSTANCES=y and devpts is mounted without the
-'newinstance' option (as in current start-up scripts) the new mount binds
-to the initial kernel mount of devpts. This mode is referred to as the
-'single-instance' mode and the current, single-instance semantics are
-preserved, i.e PTYs are common across the system.
-
-The only difference between this single-instance mode and the legacy mode
-is the presence of new, '/dev/pts/ptmx' node with permissions 0000, which
-can safely be ignored.
-
-If CONFIG_DEVPTS_MULTIPLE_INSTANCES=y and 'newinstance' option is specified,
-the mount is considered to be in the multi-instance mode and a new instance
-of the devpts fs is created. Any ptys created in this instance are independent
-of ptys in other instances of devpts. Like in the single-instance mode, the
-/dev/pts/ptmx node is present. To effectively use the multi-instance mode,
-open of /dev/ptmx must be a redirected to '/dev/pts/ptmx' using a symlink or
-bind-mount.
-
-Eg: A container startup script could do the following:
-
-	$ chmod 0666 /dev/pts/ptmx
-	$ rm /dev/ptmx
-	$ ln -s pts/ptmx /dev/ptmx
-	$ ns_exec -cm /bin/bash
-
-	# We are now in new container
-
-	$ umount /dev/pts
-	$ mount -t devpts -o newinstance lxcpts /dev/pts
-	$ sshd -p 1234
-
-where 'ns_exec -cm /bin/bash' calls clone() with CLONE_NEWNS flag and execs
-/bin/bash in the child process.  A pty created by the sshd is not visible in
-the original mount of /dev/pts.
+As an option instead of placing a /dev/ptmx device node at /dev/ptmx
+it is possible to place a symlink to /dev/pts/ptmx at /dev/ptmx or
+to bind mount /dev/ptx/ptmx to /dev/ptmx.  If you opt for using
+the devpts filesystem in this manner devpts should be mounted with
+the ptmxmode=0666, or chmod 0666 /dev/pts/ptmx should be called.
 
 Total count of pty pairs in all instances is limited by sysctls:
 kernel.pty.max = 4096		- global limit
-kernel.pty.reserve = 1024	- reserve for initial instance
+kernel.pty.reserve = 1024	- reserved for filesystems mounted from the initial mount namespace
 kernel.pty.nr			- current count of ptys
 
 Per-instance limit could be set by adding mount option "max=<count>".
 This feature was added in kernel 3.4 together with sysctl kernel.pty.reserve.
 In kernels older than 3.4 sysctl kernel.pty.max works as per-instance limit.
-
-User-space changes
-------------------
-
-In multi-instance mode (i.e '-o newinstance' mount option is specified at least
-once), following user-space issues should be noted.
-
-1. If -o newinstance mount option is never used, /dev/pts/ptmx can be ignored
-   and no change is needed to system-startup scripts.
-
-2. To effectively use multi-instance mode (i.e -o newinstance is specified)
-   administrators or startup scripts should "redirect" open of /dev/ptmx to
-   /dev/pts/ptmx using either a bind mount or symlink.
-
-	$ mount -t devpts -o newinstance devpts /dev/pts
-
-   followed by either
-
-	$ rm /dev/ptmx
-	$ ln -s pts/ptmx /dev/ptmx
-	$ chmod 666 /dev/pts/ptmx
-   or
-	$ mount -o bind /dev/pts/ptmx /dev/ptmx
-
-3. The '/dev/ptmx -> pts/ptmx' symlink is the preferred method since it
-   enables better error-reporting and treats both single-instance and
-   multi-instance mounts similarly.
-
-   But this method requires that system-startup scripts set the mode of
-   /dev/pts/ptmx correctly (default mode is 0000). The scripts can set the
-   mode by, either
-
-   	- adding ptmxmode mount option to devpts entry in /etc/fstab, or
-	- using 'chmod 0666 /dev/pts/ptmx'
-
-4. If multi-instance mode mount is needed for containers, but the system
-   startup scripts have not yet been updated, container-startup scripts
-   should bind mount /dev/ptmx to /dev/pts/ptmx to avoid breaking single-
-   instance mounts.
-
-   Or, in general, container-startup scripts should use:
-
-	mount -t devpts -o newinstance -o ptmxmode=0666 devpts /dev/pts
-	if [ ! -L /dev/ptmx ]; then
-		mount -o bind /dev/pts/ptmx /dev/ptmx
-	fi
-
-   When all devpts mounts are multi-instance, /dev/ptmx can permanently be
-   a symlink to pts/ptmx and the bind mount can be ignored.
-
-5. A multi-instance mount that is not accompanied by the /dev/ptmx to
-   /dev/pts/ptmx redirection would result in an unusable/unreachable pty.
-
-	mount -t devpts -o newinstance lxcpts /dev/pts
-
-   immediately followed by:
-
-	open("/dev/ptmx")
-
-    would create a pty, say /dev/pts/7, in the initial kernel mount.
-    But /dev/pts/7 would be invisible in the new mount.
-
-6. The permissions for /dev/pts/ptmx node should be specified when mounting
-   /dev/pts, using the '-o ptmxmode=%o' mount option (default is 0000).
-
-	mount -t devpts -o newinstance -o ptmxmode=0644 devpts /dev/pts
-
-   The permissions can be later be changed as usual with 'chmod'.
-
-	chmod 666 /dev/pts/ptmx
-
-7. A mount of devpts without the 'newinstance' option results in binding to
-   initial kernel mount.  This behavior while preserving legacy semantics,
-   does not provide strict isolation in a container environment. i.e by
-   mounting devpts without the 'newinstance' option, a container could
-   get visibility into the 'host' or root container's devpts.
-   
-   To workaround this and have strict isolation, all mounts of devpts,
-   including the mount in the root container, should use the newinstance
-   option.

+		第十九章:内联汇编
+
+在特定架构的代码中,你也许需要内联汇编来使用 CPU 接口和平台相关功能。在需要
+这么做时,不要犹豫。然而,当 C 可以完成工作时,不要无端地使用内联汇编。如果
+可能,你可以并且应该用 C 和硬件交互。
+
+考虑去写通用一点的内联汇编作为简明的辅助函数,而不是重复写下它们的细节。记住
+内联汇编可以使用 C 参数。
+
+大而特殊的汇编函数应该放在 .S 文件中,对应 C 的原型定义在 C 头文件中。汇编
+函数的 C 原型应该使用 “asmlinkage”。
+
+你可能需要将你的汇编语句标记为 volatile,来阻止 GCC 在没发现任何副作用后就
+移除了它。你不必总是这样做,虽然,这样可以限制不必要的优化。
+
+在写一个包含多条指令的单个内联汇编语句时,把每条指令用引号字符串分离,并写在
+单独一行,在每个字符串结尾,除了 \n\t 结尾之外,在汇编输出中适当地缩进下
+一条指令:
+
+	asm ("magic %reg1, #42\n\t"
+	     "more_magic %reg2, %reg3"
+	     : /* outputs */ : /* inputs */ : /* clobbers */);
+
+
+		第二十章:条件编译
+
+只要可能,就不要在 .c 文件里面使用预处理条件;这样做让代码更难阅读并且逻辑难以
+跟踪。替代方案是,在头文件定义函数在这些 .c 文件中使用这类的条件表达式,提供空
+操作的桩版本(译注:桩程序,是指用来替换一部分功能的程序段)在 #else 情况下,
+再从 .c 文件中无条件地调用这些函数。编译器会避免生成任何桩调用的代码,产生一致
+的结果,但逻辑将更加清晰。
+
+宁可编译整个函数,而不是部分函数或部分表达式。而不是在一个表达式添加 ifdef,
+解析部分或全部表达式到一个单独的辅助函数,并应用条件到该函数内。
+
+如果你有一个在特定配置中可能是未使用的函数或变量,编译器将警告它定义了但未使用,
+标记这个定义为 __maybe_unused 而不是将它包含在一个预处理条件中。(然而,如果
+一个函数或变量总是未使用的,就直接删除它。)
+
+在代码中,可能的情况下,使用 IS_ENABLED 宏来转化某个 Kconfig 标记为 C 的布尔
+表达式,并在正常的 C 条件中使用它:
+
+	if (IS_ENABLED(CONFIG_SOMETHING)) {
+		...
+	}
+
+编译器会无条件地做常数合并,就像使用 #ifdef 那样,包含或排除代码块,所以这不会
+带来任何运行时开销。然而,这种方法依旧允许 C 编译器查看块内的代码,并检查它的正确
+性(语法,类型,符号引用,等等)。因此,如果条件不满足,代码块内的引用符号将不存在,
+你必须继续使用 #ifdef。
+
+在任何有意义的 #if 或 #ifdef 块的末尾(超过几行),在 #endif 同一行的后面写下
+注释,指出该条件表达式被使用。例如:
+
+	#ifdef CONFIG_SOMETHING
+	...
+	#endif /* CONFIG_SOMETHING */
+
