In state SMC_INIT smc_poll() delegates polling to the internal CLC socket. This means, once the connect worker has finished its kernel_connect() step, the poll wake-up may occur. This is not intended. The wake-up should occur from the wake up call in smc_connect_work() after __smc_connect() has finished. Thus in state SMC_INIT this patch now calls sock_poll_wait() on the main SMC socket.
