From foo@baz Tue Apr 9 12:12:43 2002 Date: Mon, 9 Apr 2007 11:52:31 -0400 (EDT) To: Greg KH From: Greg Kroah-Hartman 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...
