From 85de5d53366f02dd0f81c9be8f435b27fb82b1f7 Mon Sep 17 00:00:00 2001 From: Bernard Metzler Date: Wed, 10 Jul 2019 08:38:00 +0000 Subject: [PATCH] RDMA/siw: Remove unnecessary kthread create/destroy printouts There is already a warning if we cannot start any thread, and stopping those threads is not worth spamming the console. This also corrects a warning from gcc: drivers/infiniband/sw/siw/siw_main.c: In function 'siw_create_tx_threads': drivers/infiniband/sw/siw/siw_main.c:91:11: warning: variable 'rv' set but not used [-Wunused-but-set-variable] Reported-by: Hulk Robot Signed-off-by: YueHaibing Signed-off-by: Bernard Metzler Signed-off-by: Jason Gunthorpe --- drivers/infiniband/sw/siw/siw_main.c | 4 +--- drivers/infiniband/sw/siw/siw_qp_tx.c | 4 ---- 2 files changed, 1 insertion(+), 7 deletions(-) diff --git a/drivers/infiniband/sw/siw/siw_main.c b/drivers/infiniband/sw/siw/siw_main.c index fd2552a9091d..f55c4e80aea4 100644 --- a/drivers/infiniband/sw/siw/siw_main.c +++ b/drivers/infiniband/sw/siw/siw_main.c @@ -88,7 +88,7 @@ static void siw_device_cleanup(struct ib_device *base_dev) static int siw_create_tx_threads(void) { - int cpu, rv, assigned = 0; + int cpu, assigned = 0; for_each_online_cpu(cpu) { /* Skip HT cores */ @@ -99,9 +99,7 @@ static int siw_create_tx_threads(void) kthread_create(siw_run_sq, (unsigned long *)(long)cpu, "siw_tx/%d", cpu); if (IS_ERR(siw_tx_thread[cpu])) { - rv = PTR_ERR(siw_tx_thread[cpu]); siw_tx_thread[cpu] = NULL; - pr_info("Creating TX thread for CPU %d failed", cpu); continue; } kthread_bind(siw_tx_thread[cpu], cpu); diff --git a/drivers/infiniband/sw/siw/siw_qp_tx.c b/drivers/infiniband/sw/siw/siw_qp_tx.c index 1c9fa8fa96e5..f0d949e2e318 100644 --- a/drivers/infiniband/sw/siw/siw_qp_tx.c +++ b/drivers/infiniband/sw/siw/siw_qp_tx.c @@ -1201,8 +1201,6 @@ int siw_run_sq(void *data) init_llist_head(&tx_task->active); init_waitqueue_head(&tx_task->waiting); - pr_info("Started siw TX thread on CPU %u\n", nr_cpu); - while (1) { struct llist_node *fifo_list = NULL; @@ -1240,8 +1238,6 @@ int siw_run_sq(void *data) siw_sq_resume(qp); } } - pr_info("Stopped siw TX thread on CPU %u\n", nr_cpu); - return 0; }
