Just mention that it will waste memory and also give *some* ballpark estimate on how much. Just looking at your laptop's /proc/slabinfo would be a good start. Oh, and it wouldn't hurt to find out when and why the minimal slab alignment got dropped down to 8 bytes. I _thought_ it was higher at some point. Presumably there was a good reason for it and you're now undoing part of it.
