Actually, that's a combination of 3 bugs, only one of them being in this commit. See current #iov_iter; AFAICS, all process_vm stuff in LTP passes with it.
BTW, what's the story with ioctl3? What I'm getting from it is "Must supply a file collection or a command", with no further explanations. Something it wants installed that just isn't there?
