From 80f1ff97d0a9d92f44d2b2dd9425afa950e58f2b Mon Sep 17 00:00:00 2001 From: Amerigo Wang Date: Mon, 25 Jul 2011 17:13:08 -0700 Subject: notifiers: cpu: move cpu notifiers into cpu.h We presently define all kinds of notifiers in notifier.h. This is not necessary at all, since different subsystems use different notifiers, they are almost non-related with each other. This can also save much build time. Suppose I add a new netdevice event, really I don't have to recompile all the source, just network related. Without this patch, all the source will be recompiled. I move the notify events near to their subsystem notifier registers, so that they can be found more easily. This patch: It is not necessary to share the same notifier.h.
