[PATCH] doc: zh_CN: fix style problems for io_ordering.txt

[Wang Wenhu]

Problems exist in the Chinese translation of io_ordering.txt.
Partly for the difference between Chinese and English character
encoding format, and the others are of the failure to comply
with the ReST markups.

 这也可以保证后面的写操作只在前面的写操作之后到达设备（这非常类似于内存
 屏障操作，mb()，不过仅适用于I/O）。
 
+A more concrete example from a hypothetical device driver::
+
+		...
+	CPU A:  spin_lock_irqsave(&dev_lock, flags)
+	CPU A:  val = readl(my_status);
+	CPU A:  ...
+	CPU A:  writel(newval, ring_ptr);
+	CPU A:  spin_unlock_irqrestore(&dev_lock, flags)
+		...
+	CPU B:  spin_lock_irqsave(&dev_lock, flags)
+	CPU B:  val = readl(my_status);
+	CPU B:  ...
+	CPU B:  writel(newval2, ring_ptr);
+	CPU B:  spin_unlock_irqrestore(&dev_lock, flags)
+		...
+
+
 假设一个设备驱动程的具体例子：
+::
 
+		...
+	CPU A:  spin_lock_irqsave(&dev_lock, flags)
+	CPU A:  val = readl(my_status);
+	CPU A:  ...
+	CPU A:  writel(newval, ring_ptr);
+	CPU A:  spin_unlock_irqrestore(&dev_lock, flags)
+		...
+	CPU B:  spin_lock_irqsave(&dev_lock, flags)
+	CPU B:  val = readl(my_status);
+	CPU B:  ...
+	CPU B:  writel(newval2, ring_ptr);
+	CPU B:  spin_unlock_irqrestore(&dev_lock, flags)
         ...
-CPU A:  spin_lock_irqsave(&dev_lock, flags)
-CPU A:  val = readl(my_status);
-CPU A:  ...
-CPU A:  writel(newval, ring_ptr);
-CPU A:  spin_unlock_irqrestore(&dev_lock, flags)
-        ...
-CPU B:  spin_lock_irqsave(&dev_lock, flags)
-CPU B:  val = readl(my_status);
-CPU B:  ...
-CPU B:  writel(newval2, ring_ptr);
-CPU B:  spin_unlock_irqrestore(&dev_lock, flags)
-        ...
+
 
 上述例子中，设备可能会先接收到newval2的值，然后接收到newval的值，问题就
 发生了。不过很容易通过下面方法来修复：
+::
 
-        ...
-CPU A:  spin_lock_irqsave(&dev_lock, flags)
-CPU A:  val = readl(my_status);
-CPU A:  ...
-CPU A:  writel(newval, ring_ptr);
-CPU A:  (void)readl(safe_register); /* 配置寄存器？*/
-CPU A:  spin_unlock_irqrestore(&dev_lock, flags)
-        ...
-CPU B:  spin_lock_irqsave(&dev_lock, flags)
-CPU B:  val = readl(my_status);
-CPU B:  ...
-CPU B:  writel(newval2, ring_ptr);
-CPU B:  (void)readl(safe_register); /* 配置寄存器？*/
-CPU B:  spin_unlock_irqrestore(&dev_lock, flags)
+		...
+	CPU A:  spin_lock_irqsave(&dev_lock, flags)
+	CPU A:  val = readl(my_status);
+	CPU A:  ...
+	CPU A:  writel(newval, ring_ptr);
+	CPU A:  (void)readl(safe_register); /* 配置寄存器？*/
+	CPU A:  spin_unlock_irqrestore(&dev_lock, flags)
+		...
+	CPU B:  spin_lock_irqsave(&dev_lock, flags)
+	CPU B:  val = readl(my_status);
+	CPU B:  ...
+	CPU B:  writel(newval2, ring_ptr);
+	CPU B:  (void)readl(safe_register); /* 配置寄存器？*/
+	CPU B:  spin_unlock_irqrestore(&dev_lock, flags)
 
 在解决方案中，读取safe_register寄存器，触发IO芯片清刷未处理的写操作，
 再处理后面的读操作，防止引发数据不一致问题。
