Yes once at a time cfu was inline too and just checked for the right
sizes and the used g*u, but it got lost in the "icache over everything else" mania which is unfortunately en vogue for quite some time in kernel land (aka 
measuring patches only based on their impact on the .text
size, not the actual performance)

But you might getter better gains by fixing this general
c*u() regression.
