From 8bf43be799d4b242ea552a14db10456446be843e Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Fri, 28 Jul 2023 15:03:18 +0000 Subject: net: annotate data-races around sk->sk_priority sk_getsockopt() runs locklessly. This means sk->sk_priority can be read while other threads are changing its value. Other reads also happen without socket lock being held. Add missing annotations where needed.
