From c579d60f0d0cd87552f64fdebe68b5d941d20309 Mon Sep 17 00:00:00 2001 From: Hangyu Hua Date: Fri, 15 Jul 2022 14:23:01 +0800 Subject: ipc: mqueue: fix possible memory leak in init_mqueue_fs() commit db7cfc380900 ("ipc: Free mq_sysctls if ipc namespace creation failed") Here's a similar memory leak to the one fixed by the patch above. retire_mq_sysctls need to be called when init_mqueue_fs fails after setup_mq_sysctls.
