From 0eb4e7ee1655b7ffd3204a35d77b809d42613cb9 Mon Sep 17 00:00:00 2001 From: Geliang Tang Date: Mon, 7 Mar 2022 12:44:31 -0800 Subject: mptcp: add tracepoint in mptcp_sendmsg_frag The tracepoint in get_mapping_status() only dumped the incoming mpext fields. This patch added a new tracepoint in mptcp_sendmsg_frag() to dump the outgoing mpext too.
