What does -stable backport tag mean?
Is this something tip:x86 or Ingo Molnar specific?
I saw quite some "easy" fixes not being added/submitted to stable
in other subsystems and doing double work going through them,
pick them out and submit them to stable is an unnecessary waste
of time and some fixes will slip through.
Is there a general approach all maintainers should handle this?
If not, maybe you could suggest your way of handling this to others?

Thanks,
