I'm sorry but that's like banning the use of heaters just because they can abused and cause fires. I think I've said this to you before but in networking we very much want to use ksize because the standard case of a 1500-byte packet has loads of extra room given by kmalloc which all goes to waste right now. If we could use ksize then we can stuff loads of metadata in that space.
