Subject: sysfs: spit a warning to users when they try to create a duplicate sysfs file
Date: Thu, 13 Sep 2007 16:41:18 -0700 [thread overview]
Message-ID: <20070913234118.GH10856@kroah.com> (raw)
In-Reply-To: <20070913233751.GA10856@kroah.com>
We want to let people know when we create a duplicate sysfs file, as
they need to fix up their code.
