Your patch is clearly based on zijun's one, it even has the same subject. A change of authorship shouldn't result in resetting the version number, it's still the same patch/series. You can always add a 'Co-developed-by:' tag to indicate that someone else contributed to a patch, or use a 'From:' tag if you only made minor changes on top of someone else's work. Not sure how to proceed best with the version number, especially since there are already 3 versions of the 'new' patch. Either option can create confusion, I guess you can continue with the new scheme, it seems the patch is almost ready to land anyway.
