   It is not necessary to return writeBuffer. MappedFile reepresents the file on disk , writeBuffer in TransientStorePool is direct buffer to temporary writing, when all the content in writeBuffer commit to file, the writterBuffer will be returned (org.apache.rocketmq.store.MappedFile#commit). So when MappedFile is destroyed, the writeBuffer should already be returned.
