BUG 解决

你必须创建/lib/modules/”uname-r” 这样一个空目录了,否则不能卸载ko模块 但是这样到可以卸载掉模块了,不过会一直有这样一个提示: rmmod: module 模块名’ not found.

如下:

[Webee210]\# pwd
/lib/modules/3.8.0-ge8e9b24
[Webee210]\# ls
modules.dep.bb
[Webee210]\#  再测试一次:

[Webee210]\# insmod ./mem-funtion-test.ko 
mem-test        initialized
[Webee210]\# rmmod ./mem-funtion-test.ko 
[Webee210]\#
