The rules haven't changed. Maintainers are doing the wrong thing. If a series is split up into multiple parts, then maintainers *must* coordinate to put the prerequisites into a single branch that can be merged into each branch handling it. However, it is still almost always better to just merge the entire series via a single tree. Make noise whenever you see this kind of breakage because it means a maintainer has done the wrong thing. g. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
