From e1ca44e85f652a6ebd657c67c394894c1fdfb403 Mon Sep 17 00:00:00 2001 From: Kuniyuki Iwashima Date: Wed, 18 Jun 2025 21:13:56 -0700 Subject: [PATCH] af_unix: Add test for consecutive consumed OOB. Let's add a test case where consecutive concumed OOB skbs stay at the head of the queue. Without the previous patch, ioctl(SIOCATMARK) assertion fails.
