From mboxrd@z Thu Jan 1 00:00:00 1970 From: David Hinds Date: Fri, 09 Feb 2001 17:30:31 +0000 Subject: Re: definition of terms (was: Re: Adding PCMCIA support to the kernel tree -- developers needed.) Message-Id: List-Id: References: In-Reply-To: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-hotplug@vger.kernel.org I think this discussion is trying to create a very difficult problem out of something that really is not that hard to handle in practice. Say you insert one hot plug device then in the next microsecond swap it out and swap in another device of the same type but that you want to configure differently. Is this really a scenario that deserves serious discussion? I would simply require serialization of hot plug agent actions and then it seems to me that 90% of the theoretical problem (and 99.999% of the real problem) goes away. If you try to redesign the entire Linux device model to handle a hot plug corner case, you're wasting your time because your changes will never be accepted; DevFS is a minor change in comparison. PCMCIA does handle these issues and the solution (serializing device configuration actions, and configuring devices based on physical location and/or device properties rather than device names) works. -- Dave _______________________________________________ Linux-hotplug-devel mailing list http://linux-hotplug.sourceforge.net Linux-hotplug-devel@lists.sourceforge.net http://lists.sourceforge.net/lists/listinfo/linux-hotplug-devel
