Yes. It is a bug, and the description reparent_to_init is likewise buggy.
I have recently realized that a number of the inital pid namespace patches have stupid little bugs in them like this. I am upset with myself for failing to code review them closely before the went in. Live and learn I guess.
So when I saw this I added this to my growing list of things I needed to review before I could assume they were done correctly.
Feel free to fix it. I'm still a couple days out from having enough time before I can start working on pid related issues.
