From 93e5116f981c82a2994344d4fa20961d384ad452 Mon Sep 17 00:00:00 2001 From: Geliang Tang Date: Mon, 7 Oct 2024 18:53:20 +0800 Subject: [PATCH] mptcp: make pm wrappers static The path manager wrappers, mptcp_pm_get_addr(), mptcp_pm_dump_addr() and mptcp_pm_set_flags() are used to switch the interfaces between in-kernel PM and userspace PM. These wrappers are defined in pm.c but only used in pm_netlink.c. It makes more sense to move them to pm_netlink.c and make them all static.
