ok - it's useful to point this out in the changelog. You can use the 
"Impact:" header we started using recently:

    Impact: cleanup, no functionality changed

See for example this upstream commit:

| commit 07454bfff151d2465ada809bbaddf3548cc1097c
| Author: Thomas Gleixner <tglx@linutronix.de>
| Date:   Sat Oct 4 10:51:07 2008 +0200
|
|     clockevents: check broadcast tick device not the clock events device
|
|     Impact: jiffies increment too fast.
 
Mathieu, any objections against the patch?
