Hi All, 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 . The tcp state change handler does not give me any clues also. Is it just to supress optimization from the GCC? Is some other thread capable of changing it, apart from the usual state_changed handler ? Am i missing something here? Can we just use memory barriers here?[refer: volatile considered harmful on LKML] Thank you ~psr -- play the game - 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
