looks odd. Was this

--- a/ipc/mq_sysctl.c~mqueue-namespace-adapt-sysctl-update-fix
+++ a/ipc/mq_sysctl.c
@@ -52,8 +52,8 @@ static int proc_mq_dointvec_minmax(ctl_t
lenp, ppos);
}
#else
-proc_handler *proc_mq_dointvec = NULL;
-proc_handler *proc_mq_dointvec_minmax = NULL;
+#define proc_mq_dointvec NULL
+#define proc_mq_dointvec_minmax NULL
#endif

static int msg_max_limit_min = MIN_MSGMAX;
