函数名称：Mark the object as not allocated and schedule RCU freeing via put_object().

函数原型：static void __delete_object(struct kmemleak_object *object)

返回类型：void

参数：

类型参数名称
struct kmemleak_object *object
663  WARN_ON(!(bject status flags & lag representing the memory block allocation status ))
664  WARN_ON(atomic_read( & bject usage count; object freed when use_count == 0 ) < 1)
670  spin_lock_irqsave( & lock, flags)
671  bject status flags 与等于lag representing the memory block allocation status 的反
672  spin_unlock_irqrestore( & lock, flags)
673  Decrement the object use_count. Once the count is 0, free the object using* an RCU callback. Since put_object() may be called via the kmemleak_free() ->* delete_object() path, the delayed RCU freeing ensures that there is no

delete_object_partLook up the metadata (struct kmemleak_object) corresponding to ptr and* delete it. If the memory block is partially freed, the function may create* additional metadata for the remaining parts of the block.
