Hi
Why do we need the socket state (for the nework layer representation of the sockets) to be volatile? It is implemented as volatile unsigned char skc_state in struct sock_common .
I personally think this is done to prevent looking up the state on the CPU registers. In other word, query is always directed toward physical memory. Yes, it lowers the perfomance but maybe it is designed that way so we won't get wrong socket state. regards, Mulyadi - To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
