this point, the disk controller will be able to copy it to disk more efficiently. This is good for performance, but the reverse is true for the logging function. To ensure that the log is absolutely reliable, it must ensure that the metadata is pre-written before the actual data is written. This is why we want to introduce the file system barrier.It is easy to understand the root cause of using barrier: Barrier itself prohibits writing data after barrier, and real chunks are written to disk com
