Why istn't dup in TCP working??

[Nitin Dhingra]

Hi,
		I used functions of socket's operation structure like 
create, bind, connect, dup etc.in the kernel for transfering data over 
TCP from the kernel. 
		Now this is working fine in 2.2.x but when I compiled my 
module in 2.4.x the first error that I get is that dup is not a 
part of socket's operation structure anymore. 
		So what is the replacement for it, I couldn't find any
in the proto_ops structure?

Regards,
Nitin
