I agree increasing the timeout is more than enough for FLR case.
However, I was considering the wait and pending functions as a utility that I can reuse towards fixing CRS in other conditions like secondary bus reset and potentially PM.
I'm planning to have a CRS session in the Linux Plumbers Conference to talk about CRS use cases.
I was going to follow up this series with secondary bus reset next once this goes in.
I'm unable to test PM. I can't promise how I fix/test it.
