I also noticed that ldconfig takes a lot of time to complete, and firefox seems also to eat much more memory than usual. Reverting the two patches (going back to vanilla rc5-git5) makes these problems go away. I am not able to test right now if only one of the patches is bogus or if both of them are concerned. As the symptoms are easy to reproduce, I guess this is some kind of brown paper bag bug and will be easy for XFS experts to spot.
