Commit-ID: b4f75d44bed1bdbb14ac704bfc38f62a3675e591 Gitweb: http://git.kernel.org/tip/b4f75d44bed1bdbb14ac704bfc38f62a3675e591 Author: Thomas Gleixner <tglx@xxxxxxxxxxxxx> AuthorDate: Tue, 9 Feb 2016 20:11:20 +0000 Committer: Ingo Molnar <mingo@xxxxxxxxxx> CommitDate: Wed, 17 Feb 2016 10:37:28 +0100 perf/core: Remove bogus UP_CANCELED hotplug state If CPU_UP_PREPARE fails the perf hotplug code calls perf_event_exit_cpu(), which is a pointless exercise. The cpu is not online, so the smp function calls return -ENXIO. So the result is a list walk to call noops. Remove it.
