There're places where manual intervention is still required as uncrustify is not ideal (unfortunately), but at least one may rely on it to do the right thing most of the time (e.g. when sending in a patch). The style itself is quite different from what we had before but making it uniform across all the codebase is the key. I also hope that it'll make the code more readable (YMMV) and less sensitive to further changes.
