It will be pushed if I get no objections before 06/12/21. So please shout if anyone has objections. Also note that after the patch there's a diff of the upstream commit vs the patch applied to the branch. This will indicate if there was any rebasing needed to apply to the stable branch. If there were code changes for rebasing (ie: not only metadata diffs), please double check that the rebase was correctly done. Queued patches are on a temporary branch at: https://github.com/cpaelzer/dpdk-stable-queue This queued commit can be viewed at: https://github.com/cpaelzer/dpdk-stable-queue/commit/5c78bf88aafdd8eca4364bf0c02c6d5a8065c98b Thanks.

This will lead to a memory leak, when a device is configured repeatedly. For example: for(...) do rte_eth_dev_configure rte_eth_rx_queue_setup rte_eth_tx_queue_setup rte_eth_dev_start rte_eth_dev_stop done Fixes: 120dc4a7dcd3 ("net/mlx5: remove device register remap") Signed-off-by: Yunjian Wang Acked-by: Viacheslav Ovsiienko --- drivers/net/mlx5/mlx5.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/net/mlx5/mlx5.c b/drivers/net/mlx5/mlx5.c index e0ba600868..3208b2eda7 100644 --- a/drivers/net/mlx5/mlx5.c +++ b/drivers/net/mlx5/mlx5.c @@ -1255,6 +1255,7 @@ mlx5_proc_priv_init(struct rte_eth_dev *dev) struct mlx5_proc_priv *ppriv; size_t ppriv_size; + mlx5_proc_priv_uninit(dev); /* * UAR register table follows the process private structure.
