is sk->reuse truly a boolean?

[Arnaldo Carvalho de Melo <acme@xxxxxxxxxxxxxxxx>]

From what I see in the code and from references in, for instance, Unix
Network Programming (W. Richard Stevens) it is, but then how can this work?

net/ipv4/tcp_ipv4.c, line 265

                if (sk->reuse > 1)
                        goto success;

In net/core/sock.c, setsockopt it just assigns 1 or 0, i.e. if userspace
passes > 1 it becomes 1, is this the intended behaviour? I think we have a 
bug in tcp_ipv4 or in core/sock.c 8)

Comments?
