Given nature of the build bug issues reported, I'm guessing you never
built this as a module :( Not sure how one instance of a missing
user marking got through but also easy to fix.
Anyhow, no need to wait before sending a v9 with those sorted.
0-day does it's job again - even better is that it's whilst it's
still your problem and not mine :)
