From f67f129e519fa87f8ebd236b6336fe43f31ee141 Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Sun, 1 Mar 2009 21:10:49 +0800 Subject: Driver core: implement uevent suppress in kobject This patch implements uevent suppress in kobject and removes it from struct device, based on the following ideas: 1,Uevent sending should be one attribute of kobject, so suppressing it in kobject layer is more natural than in device layer. By this way, we can do it for other objects embedded with kobject. 2,It may save several bytes for each instance of struct device.(On my omap3(32bit ARM) based box, can save 8bytes per device object) This patch also introduces dev_set|get_uevent_suppress() helpers to set and query uevent_suppress attribute in case to help kobject as private part of struct device in future.
