Please use the customary changelog style we use in the kernel:

  " Current code does (A), this has a problem when (B).
    We can improve this doing (C), because (D)."

(Of if it's a cleanup only with no functional effects then please 
state it so in the title and changelog.)

Thanks,

        Ingo
