When we run the cpuhotplug03 test case on the arm64 machine, we conclude that no error occurs when the cpuhotplug03 case is executed alone, but once the cpuset_sched_domains case is executed first, After cpuhotplug03 is executed, the error "cpuhotplug03 1 TFAIL: No cpuhotplug_do_spin_loop processes found on" occurs. The cpuset_sched_domains test case changes the value of cpuset.sched_load_balance in the cpuset cgroup subsystem, but does not restore the value at the end of the test. Modify the cpuset_funcs.sh file. The test result shows that the problem is solved successfully.
