The reason this technique is called the "cheap read-write lock" is that you are using different synchronization mechanisms for reads and writes.
之所以将这种技术称之为 “开销较低的读-写锁” 是因为您使用了不同的同步机制进行读写操作。
The time (microseconds) to perform the transaction for a single node were 1877 with regular locking, 1225 with an explicit write lock, and 181 using a "dirty interface".

If you don't adhere to this approach in prioritizing writer threads using pthread_setschedprio, then given the nature of read-write lock, it is easy to see how writer threads could starve.

On the surface it looks as though lock elision allows us to write thread safe code without any synchronization penalty for using in cases where it really wasn't needed.
从表面上看，锁省略似乎可以允许我们不必忍受同步带来的负担，就可以编写线程安全的代码了，前提是在同步的确是多余的情况下。
Once an exclusive lock has been issued, no other read or write operations can take place.
在发出独占锁定后，其他的读或写操作将不会再发生。
User C will get the write access once user B releases the file lock.

The s lock allows concurrent applications that use read-only queries to access the target table, but applications attempting to write data to the table are prevented from doing so.

This is due to the way in which JFS2 is implemented with a write-exclusive inode lock, allowing multiples users to read the same file simultaneously.
这是因为JFS2在实现时使用了写独占(write - exclusive)索引节点锁，允许多个用户同时读取相同的文件。
That write-lock would then block other transactions.
