I don't think random patches should be sent to stable just because
they appeared in mainline. Plus, I don't think I'm making new rules:

submit-checklist.rst:

13) Has been build- and runtime tested with and without ``CONFIG_SMP``
and
    ``CONFIG_PREEMPT.``

stable-kernel-rules.rst:

Rules on what kind of patches are accepted, and which ones are not,
into the "-stable" tree:

 - It must be obviously correct and tested.
 - It must fix a real bug that bothers people (not a, "This could be a
   problem..." type thing).

See jacek.anaszewski@xxxxxxxxx 's explanation.
