Cascardo, I was trying to reproduce the issue as Po-Hsu Lin has mentioned (#3), but the hotplug leaves the system in the same state (shows this output): ``` ./cpu-hotplug/cpu-on-off-test.sh pid 21291's current affinity mask: ffffffffffffffffffffffffffffffff pid 21291's new affinity mask: 1 CPU online/offline summary: present_cpus = 0-127 present_max = 127 Cpus in online state: 0-127 Cpus in offline state: 0 Limited scope test: one hotplug cpu (leaves cpu in the original state): online to offline to online: cpu 127 ``` I was running this way: ``` ubuntu@gulpin:~/ubuntu-hirsute/tools/testing/selftests$ make TARGETS=net ./cpu-hotplug/cpu-on-off-test.sh ./net/reuseport_bpf_cpu ``` Let me know if there's anything else needed.
