(re the duplication) Where do you see duplication? sctp_setsockopt_nodelay does the following things: - verifies optlen, returns -EINVAL if it doesn't match - calls get_user, returns -EFAULT on error - converts the value from get_user to a boolean and assigns it to sctp_sk(sk)->nodelay - returns 0. sctp_sock_set_nodelay does: - call lock_sock - assign true to sctp_sk(sk)->nodelay - call release_sock - does not return an error code _______________________________________________ linux-nvme mailing list linux-nvme@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-nvme
