However, this code is incorrect (it was incorrect before you touched it, so not your fault). Moving it to a list makes it a lot worse though because it introduces the possibility of dereferencing an invalid pointer. The hooks need to grab the spinlock before parsing the list. I've got a patch which I'll post. I'd appreciate it if you can test also. In actual fact, I'd like to replace the spinlock with a mutex, but that requires some auditing to make sure there aren't any users from an atomic context. g. -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
