Ok, guys, stop the crazy. That's another of those "ok, that's just ttoally stupid and clearly too complex" ideas that I would never pull. I should seriously suggest that people just stop discussing architectural details on the pm list if they all end up being this level of crazy. The sane thing to do is to just totally ignore the async layer on PCI bridges and other things that only have a late-suspend/early-resume thing. No need for the above kind of obviously idiotic crap. However, my point was really that we wouldn't even have _needed_ that kind of special case if we had just decided to let the subsystems do it. But whatever. At worst, the PCI layer can even just mark such devices with just late/early suspend/resume as being asynchronous, even though that ends up resulting in some totally pointless async work that doesn't do anything. But please guys - reign in the crazy ideas on the pm list. It's not like our suspend/resume has gotten so stable as to be boring, and we want it to become unreliable again.
