This is starting to become a little unmanageable. :-) I'm sure we could keep adding more and more cleanup patches with each version of the series, but we don't really have to let the first fixes wait for all cleanups and fix the whole world in a single series. So I decided to start with a prefix of this series and applied patches 1-22, which all had received review before and were easy to compare against the previous version. If you don't object, I'd send a pull request for those without waiting for the rest. If the other patches still need some changes, you can start a new patch series at v1 containing the remaining patches. (No need to resend them now, though, I can review them in this series.) Does this make sense to you? Kevin
