Yeah.  I know.  And it's way more involved and controversial to change
ksock_tunables.

No one will ever think about types again if Sparse stops complaining.
It's better to keep the error message instead of silencing it in a less
than ideal way because it means we have to think about types.
Eventually someone will get sick of the warning and write a huger patch
that rewrites a lot of code.
