From: Tal Shnaiderman Date: Tue, 16 Mar 2021 13:28:19 +0000 (+0200) Subject: eal: rename thread TLS API X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=1325a1ffd98dcec9a083e3800833211822c37e74;p=dpdk.git eal: rename thread TLS API Rename the key opaque pointer from rte_tls_key to rte_thread_key to avoid confusion with transport layer security. Also rename and remove the "_tls" term from the following functions to avoid redundancy: rte_thread_tls_key_create rte_thread_tls_key_delete rte_thread_tls_value_set rte_thread_tls_value_get Suggested-by: Vladimir Medvedkin Suggested-by: Morten Brørup Signed-off-by: Tal Shnaiderman Acked-by: Morten Brørup --- diff --git a/doc/guides/rel_notes/release_21_05.rst b/doc/guides/rel_notes/release_21_05.rst index fb965fec32..c187f1fa27 100644 --- a/doc/guides/rel_notes/release_21_05.rst +++ b/doc/guides/rel_notes/release_21_05.rst @@ -130,6 +130,10 @@ API Changes Also, make sure to start the actual text at the margin. ======================================================= +* eal: The experimental TLS API added in ``rte_thread.h`` has been renamed + from ``rte_thread_tls_*`` to ``rte_thread_*`` to avoid naming redundancy + and confusion with the transport layer security term. + ABI Changes ----------- diff --git a/drivers/net/mlx5/linux/mlx5_flow_os.c b/drivers/net/mlx5/linux/mlx5_flow_os.c index 732b1b2dd8..893f00b824 100644 --- a/drivers/net/mlx5/linux/mlx5_flow_os.c +++ b/drivers/net/mlx5/linux/mlx5_flow_os.c @@ -7,12 +7,12 @@ #include /* Key of thread specific flow workspace data. */ -static rte_tls_key key_workspace;
