Regardless of whether this is the problem, banning ksize because it can be abused is like banning cars because they can kill people.
For example, Ethernet skbs are 1500 bytes long, so using ksize we could potentially use the left-over memory for temporary storage. Without it all this memory goes to waste. On a machine that's doing a lot of networking this could save a signifcant amount of memory.
