From 238064f13d057390a8c5e1a6a80f4f0a0ec46499 Mon Sep 17 00:00:00 2001 From: Dexuan Cui Date: Tue, 27 Mar 2018 15:01:02 -0700 Subject: [PATCH] Drivers: hv: vmbus: do not mark HV_PCIE as perf_device The pci-hyperv driver's channel callback hv_pci_onchannelcallback() is not really a hot path, so we don't need to mark it as a perf_device, meaning with this patch all HV_PCIE channels' target_cpu will be CPU0.
