| Subject: cpupowerutils: bench - Fix cpu online check |
| |
| From: Abhishek Goel <huntbag@linux.vnet.ibm.com> |
| |
| |
| [ Upstream commit 53d1cd6b125fb9d69303516a1179ebc3b72f797a ] |
| |
| cpupower_is_cpu_online was incorrectly checking for 0. This patch fixes |
| this by checking for 1 when the cpu is online. |
