Well, you are the boss here, but frankly, I don't think it is obvious
enough. I had to look twice and very closely to understand the logic.
Not because of the function name, but for the reason why 'is_suspend' is
true despite being in _shutdown(). Adrian was wondering about it the
first time, too. So, I honestly think the comment is

  for a maintainer -> superfluous
  for a part-time-MMC-core-hacker -> helpful to remember
  for someone new to the code -> essential

Something like this.
