sorry, sending again, first one had html in it..
Any update on this one?
I'm seeing this in every boot. I patched this by changing led_trigger_register
and led_trigger_register_simple as macros which creates a static lock_class_key
like this:
-extern int led_trigger_register(struct led_trigger *trigger);
+
+extern int __led_trigger_register_key(struct led_trigger *trigger,
+ struct lock_class_key *key);
+#ifdef CONFIG_LOCKDEP
+#define led_trigger_register(trigger) \
+({ \
+ static struct lock_class_key __key; \
+ \
+ __led_trigger_register_key(trigger, &__key); \
+})
+#else
+#define led_trigger_register(trigger) \
+ __led_trigger_register_key(trigger, NULL)
+#endif
+
But should every trigger has own key? With my patch all the triggers from
vt/keyboard.c are using the same key. Is that a problem? I have not seen any
problems with that patch and after that I can see this
