From 631a4b3ddc7831b20442c59c28b0476d0704c9af Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Tue, 9 Jul 2024 02:02:26 +0200 Subject: [PATCH] netfilter: nfnetlink_queue: drop bogus WARN_ON Happens when rules get flushed/deleted while packet is out, so remove this WARN_ON. This WARN exists in one form or another since v4.14, no need to backport this to older releases, hence use a more recent fixes tag.
