NOVA has four kinds of log entries: File write entry describes a write to a contiguous range of pmem pages, Dentry describes a file/directory being added or removed from a directory, Setattr entry is used for updating inode attributes, Link change entry describes link changes to an inode, e.g. link/unlink. All of them are aligned to 8 bytes.
