This should be Signed-off-by not Acked-by.  The reason is that the
signoffs track whose hands the patch passes through.  If you send
Scott's patch to me, it must have your signoff.  If Scott sends the
patch directly to me and then you OK it on the list, then I'll add
Acked-by.  I've assumed your acquiescence to correcting this in my tree.
