From 3fff88186f047627bb128d65155f42517f8e448f Mon Sep 17 00:00:00 2001 From: Matthieu Baerts Date: Fri, 9 Dec 2022 16:28:08 -0800 Subject: mptcp: remove MPTCP 'ifdef' in TCP SYN cookies To ease the maintenance, it is often recommended to avoid having #ifdef preprocessor conditions. Here the section related to CONFIG_MPTCP was quite short but the next commit needs to add more code around. It is then cleaner to move specific MPTCP code to functions located in net/mptcp directory. Now that mptcp_subflow_request_sock_ops structure can be static, it can also be marked as "read only after init".
