Hi magicyan2030, welcome to the openEuler Community.
I'm the Bot here serving you. You can find the instructions on how to interact with me at

If you have any questions, please contact the SIG: Kernel, and any of the maintainers: @Xie XiuQi, @YangYingliang, @成坚 (CHENG Jian).

正常的percpu使用，非问题

NR_CPUS为1024，所以index只能是0~1023,边界值1024不存在，另外当前检测点possible cpu数量是根据上限cpu设置，非问题

已确认非问题，issue 关闭。
谢谢
