The " + __must_be_array(x)" should be inside the parentheses.

Indeed. How do I send "v2" patch?

If you use git-send-email, you can add the "-v2" option to change the subject prefix from "PATCH" to "PATCH v2". It's generally a good idea to add a note explaining what changed from previous versions. You can use the --annotate option to give you a chance to edit the message before sending it. You would add a note below the "---" line with an explanation of the change from the previous version. (There's also the "notes" feature of git for maintaining such explanations, but it's kind of finicky. See "man git-notes".)
