[PATCH] cpupowerutils: bench - Fix cpu online check Abhishek Goel <huntbag@linux.vnet.ibm.com> - 2017-09-18 13:50 +0200

| Subject | [PATCH] cpupowerutils: bench - Fix cpu online check |
| Message-ID | <ur2IO-5LK-7@gated-at.bofh.it> |
cpupower_is_cpu_online returns 1 when cpu is online. But in function
set_cpufreq_governor, it was incorrectly checking for 0 in case cpu is
online.
