[重现步骤]：
1）安装kernel-debug等内核：
rpm -ivh http://ci-storage.alibaba.net/kernel/anolis8/ck-4.19/x86_64/20220919_465/kernel-debug-core-4.19.91-465.git.f167f3665.an8.x86_64.rpm
http://ci-storage.alibaba.net/kernel/anolis8/ck-4.19/x86_64/20220919_465/kernel-debug-modules-4.19.91-465.git.f167f3665.an8.x86_64.rpm
rpm -ivh http://ci-storage.alibaba.net/kernel/anolis8/ck-4.19/x86_64/20220919_465/kernel-debug-4.19.91-465.git.f167f3665.an8.x86_64.rpm
rpm -ivh http://ci-storage.alibaba.net/kernel/anolis8/ck-4.19/x86_64/20220919_465/kernel-debug-devel-4.19.91-465.git.f167f3665.an8.x86_64.rpm
rpm -ivh http://ci-storage.alibaba.net/kernel/anolis8/ck-4.19/x86_64/20220919_465/kernel-headers-4.19.91-465.git.f167f3665.an8.x86_64.rpm
2）reboot环境使得新内核生效
3）modprobe rcutorture torture_type=busted
4）sleep 450
5）rmmod rcutorture
6）modprobe rcutorture torture_type=busted_srcud
7）sleep 450
8）rmmod rcutorture


[期望结果]：
rcutorture测试pass
[实际结果]：
defaults测试集下busted和busted_srcud用例执行失败
