And syzbot is also complaining [2], correctly, that you can't pass FOLL_LONGTERM to pin_user_pages_locked(). And the patch right before it, while correct as it stands, should end up being unnecessary, because Daniel is taking a different approach. So probably best to drop both of those from mmotm and -next.
