From 4628803062d93dadc6ba8e801fd075526904a38c Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 9 Apr 2007 11:52:31 -0400 Subject: kobject core: remove rwsem from struct subsystem It isn't used at all by the driver core anymore, and the few usages of it within the kernel have now all been fixed as most of them were using it incorrectly. So remove it. Now the whole struct subsys can be removed from the system, but that's for a later patch...
