Thanks for looking at the patch Joe, Christoph pointed this out also.
Solution is going to take a different approach and not touch the column
width in /proc/slabinfo for the record, although it does not really
matter now, I think that anyone parsing /proc/slabinfo would be using
whitespace because the name field is already variable length.

Anyways, new patch to come.

thanks,
Tobin.
