I found this while checking how DCCP handles duplicate bind operations;
it seems it is a remainder of earlier code and now defunct.

[INET]: sk_reuse is valbool

sk_reuse is declared as "unsigned char", but is set as type valbool in net/core/sock.c.
There is no other place in net/ where sk->sk_reuse is set to a value > 1, so the test 
"sk_reuse > 1" can not be true.
