From fb69c3907ead36b9e9f41ea6f0d0e0ae10a38a47 Mon Sep 17 00:00:00 2001 From: Nathan Lynch Date: Sat, 25 Jun 2005 14:55:05 -0700 Subject: [PATCH] [PATCH] generate hotplug events for cpu online We already do kobject_hotplug for cpu offline; this adds a kobject_hotplug call for the online case. This is being requested by developers of an application which wants to be notified about both kinds of events.
