From 4f47d5d507d6f211ebceac76a5f0b83c2eae154b Mon Sep 17 00:00:00 2001 From: Poorva Sonparote Date: Fri, 19 Nov 2021 12:41:34 -0800 Subject: [PATCH] ipv4: Exposing __ip_sock_set_tos() in ip.h Making the static function __ip_sock_set_tos() from net/ipv4/ip_sockglue.c accessible by declaring it in include/net/ip.h The reason for doing this is to use this function to set IP_TOS value in mptcp_setsockopt() without the lock.
