Thanks for the report and the testing Done, it's commit e386dfc56f83 ("fget: clarify and improve __fget_files() implementation") in my tree now. I didn't mark it as "Fixes:" or for stable, because I can't imagine that it matters in real life. But then it struck me that Greg has mentioned that he ends up getting a lot of performance regression reports for people testing stable and they can be distracting. So I'm adding a stable cc here just so people are aware of this as a "yeah, will-it-scale.poll2 performance regression has been reported, has a fix available if somebody cares".
