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.
