求翻译：Suppose that a pointer ptr points to a data structure that is protected by RCU. It is forbidden to simply de-reference the pointer, but rcu_dereference(ptr) must be invoked before and the result be dereferenced. Additionally, the code that de-references the pointer and uses the result needs to be embraced by calls to r是什么意思？

假设 ptr 指针指向受区重案组的数据结构。禁止将只需取消引用指针，但之前必须调用 rcu_dereference(ptr)，结果是取消引用。此外，de-references 指针并使用结果的代码需要调用 rcu_read_lock 和 rcu_read_unlock 所接受：
