Call to rewrite swsusp
Talking with some people last night it seems we need to redo the swsusp (driver). From what I've been told and have seen (from the code) it doesn't talk to the generic subsystems (like block layer, network layer etc). From talks with some kernel developers, they tell me we would have to modify all the drivers to properly handle system suspends. Is it not APM/ACPI's job to bring down the system to a stable state when suspending the machine?
The swsusp should be asking all the generic subsystems. When the machine is about to be suspended it should flush any read/write buffers, stop processing packets and other things.
Am I totally wrong on this? :-)
