This particular fix only goes through the rt tree because it is only a bug when full rt is enabled. When rt is enabled, spin_locks become mutexes, and thus can not be used when preemption is disabled. The rt tree introduced a local_lock() to remove open coded preempt disabling and also to help annotate places that need per cpu protections. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
