From a045171f875cd61f690981a78ab98fbd137c938b Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 3 Dec 2007 21:16:20 -0700 Subject: [PATCH] kobject: convert ibmasm to use kref, not kobject MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The IBM asm driver is using a kobject only for reference counting, nothing else. So switch it to use a kref instead, which is all that is needed, and is much smaller.
