From 6e32d479db6079dd5d4309aa66aecbcf2664a5fe Mon Sep 17 00:00:00 2001 From: Fenghua Yu Date: Tue, 13 Nov 2012 11:32:43 -0800 Subject: [PATCH] kernel/cpu.c: Add comment for priority in cpu_hotplug_pm_callback cpu_hotplug_pm_callback should have higher priority than bsp_pm_callback which depends on cpu_hotplug_pm_callback to disable cpu hotplug to avoid race during bsp online checking. This is to hightlight the priorities between the two callbacks in case people may overlook the order. Ideally the priorities should be defined in macro/enum instead of fixed values. To do that, a seperate patchset may be pushed which will touch serveral other generic files and is out of scope of this patchset.
