现在定义更乱了……

rt-thread/include/rtdef.h

Lines 495 to 514 in 3283f54

	struct rt_spinlock
	{
	rt_hw_spinlock_t lock;
	#if defined(RT_DEBUGING_SPINLOCK)
	void *owner;
	void *pc;
	#endif /* RT_DEBUGING_SPINLOCK */
	};
	typedef struct rt_spinlock rt_spinlock_t;
	#ifndef RT_SPINLOCK_INIT
	#define RT_SPINLOCK_INIT {{0}} // default
	#endif /* RT_SPINLOCK_INIT */
	#else
	typedef rt_ubase_t rt_spinlock_t;
	struct rt_spinlock
	{
	rt_spinlock_t lock;
	};

一下是

typedef struct rt_spinlock rt_spinlock_t;
 struct rt_spinlock 
 { 
     rt_hw_spinlock_t lock;
 }; 

非 SMP 又是

 typedef rt_ubase_t rt_spinlock_t;
 struct rt_spinlock 
 { 
     rt_spinlock_t lock; 
 };

让人摸不着头脑

非smp时， rt_spinlock_t 的值就会通过宏传到rt_hw_interrupt_enable（level）里面去，所以非smp的rt_spinlock_t 就得是个常量

很久以前就是这种用法了，我尝试改过，结果非smp上面根本行不通

先不讨论具体怎么改。从原则来说，如果改 rt_spinlock_t 为结构体在非 SMP 遇到使用的问题，也得是纠正错误的用法呀。非 SMP 的时候当作整型来用，这种设计不是很合理。这样搞下去，代码会越来越乱，到处是莫名其妙的兼容逻辑。
