各位专家好，客户提了个问题如下：
patch8575528这个补丁针对的bug触发条件是什么？现在里有一套库在用10.2.0.4，是否需要安装.
我查下相关mos，发现bug信息无法显示：麻烦各位专家帮忙分析下，谢谢。

鹏松，我看了一下：
首先起因是
Bug 6795880 Session spins / OERI after 'kksfbc child completion' wait - superceded
修复 6795880 带来了BUG，8575528 是用来修复的：
Bug 8575528 Missing entries in V$MUTEX_SLEEP.location
Bug 6795880 的问题是：
A session may go into an infinite spin just after a wait for 'kksfbc child completion'.
影响版本：
11.1.0.6
10.2.0.4
10.2.0.3
而 8575528 主要是合并了 6795880 并且修复了视图的显示问题：
Null mutex locations may be seen in V$MUTEX_SLEEP or a core dump encountered in a call from kqlfMutexClnFetch() to strcpy().
所以，如果用户并未遇到 'kksfbc child completion' 的 spin 问题，就可以不应用 8575528 。
我的理解，这个问题遇到的概率应该很低。
