Hence we don't need to try to guess from the socket retcode if this failure is because the queue is about to be torn down or not. We are perfectly safe to just fail it, the request will not be cancelled later on. This solves possible very long shutdown delays when the users issues a 'nvme disconnect-all' Reported-by: Daniel Wagner <dwagner@...e.de> Signed-off-by: Sagi Grimberg <sagi@...mberg.me> Signed-off-by: Christoph Hellwig <hch@....de> Signed-off-by: Sasha Levin <sashal@...nel.org> --- drivers/nvme/host/tcp.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/drivers/nvme/host/tcp.c b/drivers/nvme/host/tcp.c index 7e3932033707..d5e162f2c23a 100644 --- a/drivers/nvme/host/tcp.c +++ b/drivers/nvme/host/tcp.c @@ -1149,8 +1149,7 @@ static int nvme_tcp_try_send(struct nvme_tcp_queue *queue) } else if (ret < 0) { dev_err(queue->ctrl->ctrl.device, "failed to send request %d\n", ret); - if (ret != -EPIPE && ret != -ECONNRESET) - nvme_tcp_fail_request(queue->request); + nvme_tcp_fail_request(queue->request); nvme_tcp_done_send_req(queue); } return ret; -- 2.35.1
