Greg, that's just pure FUD. We don't say that spinlocks are a bad thing
because we can't come up with an exhaustive list of places where we need
We'll do plenty of checks at checkpoint time.
We'll do plenty of checks at runtime.
Neither will work completely on its own, and neither will be exhaustive.
The way this will work is just as Serge said: in true Linux style, we'll
add more places users of process_deny_checkpoint() incrementally as we
find them and as people complain. We'll also be incrementally removing
them as we add functionality.
