This macro can do all this for us, so keep the code simple. Signed-off-by: Christophe JAILLET --- A similar patch has also been sent. It was replacing the kmalloc/strcpy/ strcat with a kasprintf. Updating 'create_singlethread_workqueue' gives an even more elegant solution. --- drivers/net/ethernet/mellanox/mlx5/core/health.c | 9 +-------- 1 file changed, 2 insertion(+), 8 deletions(-) diff --git a/drivers/net/ethernet/mellanox/mlx5/core/health.c b/drivers/net/ethernet/mellanox/mlx5/core/health.c index 9ff163c5bcde..160f852b7bbe 100644 --- a/drivers/net/ethernet/mellanox/mlx5/core/health.c +++ b/drivers/net/ethernet/mellanox/mlx5/core/health.c @@ -797,19 +797,13 @@ void mlx5_health_cleanup(struct mlx5_core_dev *dev) int mlx5_health_init(struct mlx5_core_dev *dev) { struct mlx5_core_health *health; - char *name; mlx5_fw_reporters_create(dev); health = &dev->priv.health; - name = kmalloc(64, GFP_KERNEL); - if (!name) - goto out_err; - strcpy(name, "mlx5_health"); - strcat(name, dev_name(dev->device)); - health->wq = create_singlethread_workqueue(name); - kfree(name); + health->wq = create_singlethread_workqueue("mlx5_health%s", + dev_name(dev->device)); if (!health->wq) goto out_err; spin_lock_init(&health->wq_lock);
