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.
