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. Fixes: dc55e35f9e81 ("ipc: Store mqueue sysctls in the ipc namespace") Signed-off-by: Hangyu Hua <hbh25y@gmail.com> Link: https://lkml.kernel.org/r/20220715062301.19311-1-hbh25y@gmail.com Signed-off-by: Eric W.
