Subject: [PATCHv2 for-next 04/12] RDMA/rtrs-clt: missing error from rtrs_rdma_conn_established
Date: Fri, 23 Oct 2020 09:43:45 +0200
Message-ID: <20201023074353.21946-5-jinpu.wang@cloud.ionos.com> (raw)
In-Reply-To: <20201023074353.21946-1-jinpu.wang@cloud.ionos.com>

From: Gioh Kim <gi-oh.kim@cloud.ionos.com>

When rtrs_rdma_conn_established returns error (non-zero value),
the error value is stored in con->cm_err and it cannot trigger
rtrs_rdma_error_recovery. Finally the error of rtrs_rdma_con_established
will be forgot.

Fixes: 6a98d71daea1 ("RDMA/rtrs: client: main functionality")
