函数名称：Scan the objects already referenced (gray objects). More objects will be* referenced and, if there are no memory leaks, all the objects are scanned.

函数原型：static void scan_gray_list(void)

返回类型：void

参数：无

1373  object等于list_entry - get the struct for this entry*@ptr: the &struct list_head pointer.*@type: the type of the struct this is embedded in.*@member: the name of the list_head within the struct.(链表后项, typeof( * object), he list of gray-colored objects (see color_gray comment below) )
1374  当gray_list不等于he list of gray-colored objects (see color_gray comment below) 循环
1375  cond_resched()
1378  如果非Memory scanning is a long process and it needs to be interruptable. This* function checks whether such interrupt condition occurred.则Scan a memory block corresponding to a kmemleak_object. A condition is* that object->use_count >= 1.
1381  tmp等于list_entry - get the struct for this entry*@ptr: the &struct list_head pointer.*@type: the type of the struct this is embedded in.*@member: the name of the list_head within the struct.(链表后项, typeof( * object), he list of gray-colored objects (see color_gray comment below) )
1385  删除链表项
1386  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

名称描述
kmemleak_scanScan data sections and all the referenced memory blocks allocated via the* kernel's standard allocators. This function must be called with the* scan_mutex held.
