I haven't seen the code, waiting for kernel.org to mirror, but I have a question...

Hrm. So does that mean this doesn't work (without -f):

  git checkout v1.4.0
  ... look around ...
  git checkout v1.2.0

I think a better (but more expensive) check would be "coming back from the detached HEAD is allowed only with '-f' or if HEAD is an ancestor of any non-HEAD ref."
