Hi, everyone. What's the purpose of journaler's prezero? It seems that it is a means of setting the edge of continuously written journal entries which is the end of journal replaying, right? If this is true, why isn't checksum used? I think checksum can achieve the same goal as the journal entry that fails the verification can serve as the end of journal replaying, and it wouldn't involve extra I/O.
