diff --git a/kernel/kprobes.c b/kernel/kprobes.c index d10ab6b9b5e0..12c0e0a02a6e 100644 --- a/kernel/kprobes.c +++ b/kernel/kprobes.c @@ -563,7 +563,7 @@ static void kprobe_optimizer(struct work_struct *work) } /* Wait for completing optimization and unoptimization */ -static void wait_for_kprobe_optimizer(void) +static void __maybe_unused wait_for_kprobe_optimizer(void) { mutex_lock(&kprobe_mutex);
wait_for_kprobe_optimizer is only used when CONFIG_SYSCTL or CONFIG_DEBUG_FS is enabled, otherwise we get a build warning kernel/kprobes.c:566:13: error: 'wait_for_kprobe_optimizer' defined but not used [-Werror=unused-function] This marks the function as __maybe_unused to shut up that warning. We could do also add more #ifdef, but that would be a little more ugly in this case.
