From 01e8ef11bc1a74e65678ed55795f59266d4add01 Mon Sep 17 00:00:00 2001 From: Parag Warudkar Date: Sat, 18 Oct 2008 20:28:50 -0700 Subject: x86: sysfs: kill owner field from attribute Tejun's commit 7b595756ec1f49e0049a9e01a1298d53a7faaa15 made sysfs attribute->owner unnecessary. But the field was left in the structure to ease the merge. It's been over a year since that change and it is now time to start killing attribute->owner along with its users - one arch at a time! This patch is attempt #1 to get rid of attribute->owner only for CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on as and when possible - avr32 will be the next since that is something I can test. Compile (make allyesconfig / make allmodconfig / custom config) and boot tested. akpm: the idea is that we put the declaration of sttribute.owner inside `#ifndef CONFIG_X86'. But that proved to be too ambitious for now because new usages kept on turning up in subsystem trees.
