Date: Fri, 27 Apr 2007 11:53:37 -0700 From: Greg Kroah-Hartman <gregkh@...e.de> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...e.de>, Adam Belay <ambx1@....rr.com> Subject: [PATCH 23/46] PNP: stop using the subsystem rwsem The rwsem is not used to protect anything, so the use of it by the PNP subsystem isn't really useful, and it's doubtful if it really did anything or not. So I've removed it.
