Subject: [PATCH] docs/zh_CN: add back the missing part in the English version
The zh_CN kasan document misses the code change in commit eefe68280c94
("kasan: Add documentation for CONFIG_KASAN_EXTRA_INFO").
Fix this by adding the translation of the missing part.
Note that this missing commit is found by checktransupdate.py

通用KASAN还报告两个辅助调用堆栈跟踪。这些堆栈跟踪指向代码中与对象交互但不直接
出现在错误访问堆栈跟踪中的位置。目前,这包括 call_rcu() 和排队的工作队列。

+启用 CONFIG_KASAN_EXTRA_INFO 选项允许 KASAN 记录和报告更多信息。目前支持的
+额外信息包括分配和释放时的 CPU 编号和时间戳。更多的信息可以帮助找到内核错误的原因,
+并将错误与其他系统事件关联起来,但代价是用额外的内存来记录更多信息(有关更多
+开销的细节,请参见 CONFIG_KASAN_EXTRA_INFO 选项的帮助文本)。
