From 46febd37f9c758b05cd25feae8512f22584742fe Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Tue, 28 Nov 2017 21:19:53 +0800 Subject: smp/hotplug: Move step CPUHP_AP_SMPCFD_DYING to the correct place Commit 31487f8328f2 ("smp/cfd: Convert core to hotplug state machine") accidently put this step on the wrong place. The step should be at the cpuhp_ap_states[] rather than the cpuhp_bp_states[]. grep smpcfd /sys/devices/system/cpu/hotplug/states 40: smpcfd:prepare 129: smpcfd:dying "smpcfd:dying" was missing before. So was the invocation of the function smpcfd_dying_cpu().
