 I think the order of the changes is not important enough to justify 
spending a lot of time and mental effort on it.  You decided, so be it.  
Thank you for your effort made with this review.

 With this series out of the way I have now posted a small clean-up for 
SBR code duplication between PCI core and an InfiniBand driver I came 
across in the course of working on this series.  See 
<https://lore.kernel.org/r/alpine.DEB.2.21.2306200153110.14084@angie.orcam.me.uk/>.

 Please have a look at your convenience.
