From 2d72fc00a1fb055e6127ccd30cac3f0eafaa98d0 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 1 Nov 2007 09:29:06 -0600 Subject: [PATCH] kobject: convert /sys/hypervisor to use kobject_create We don't need a kset here, a simple kobject will do just fine, so dynamically create the kobject and use it. We also rename hypervisor_subsys to hypervisor_kset to catch all users of the variable.
