This being a performance improvement rather than a plain bug fix series, I'm not entirely certain about backporting here. My current thinking is to put this into 4.10 (Jürgen was kind enough to do the backporting work already), but not into any older trees. Otoh at SUSE we already have this in our 4.9-based branch as well, and if other consumers of that or the 4.8 branch would mostly agree it should go there, I could certainly be convinced. It is imo out of question of putting it into 4.7 or older.
