OTOH, skb allocation uses kmalloc don't they? So you could still use
SLOB ksize for that I guess.

Yes I was referring to the data portion which is kmalloc'ed.
That is also why I'm interested in ksize because a priori we
don't know exactly how big it's going to be.  However, we do
know that statistically 1500 will dominate.

I'm not interested in ksize for kmem_cache at all.  So in fact
we could have something simpler that's based on kmalloc's rounding
algorithm instead.
