From 3514faca19a6fdc209734431c509631ea92b094e Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 16 Oct 2007 10:11:44 -0600 Subject: kobject: remove struct kobj_type from struct kset We don't need a "default" ktype for a kset. We should set this explicitly every time for each kset. This change is needed so that we can make ksets dynamic, and cleans up one of the odd, undocumented assumption that the kset/kobject/ktype model has. This patch is based on a lot of help from Kay Sievers.
