Did you mean revert commit (3aba1030)?
Sorry, I think I led to a misunderstanding. I mean commit (86434744) is the trigger of the problem I replied
in email https://lore.kernel.org/linux-s390/45a19f8b-1b64-3459-c28c-aebab4fd8f1e@xxxxxxxxxxxxxxxxx/#t, not 
the problem that commit (3aba1030) resolved for.

So I think the final solution is to remove the following lines from smc_connection() based on the current code.
if (smc->use_fallback) {
	sock->state = rc ? SS_CONNECTING : SS_CONNECTED;
	goto out;
}

Thanks,
