For new code - it would have to be in three commits. For existing code,
how you are going to achieve it with keeping full bisectability?
Remember that each commits goes to different branch and/or tree! It's
probably doable within two Linux releases with some header wrappers...
but is it worth the effort just for "consistency"?

All of them have the same bisectability problems...
