Understood. If that's the only time it happened, I would be happy with that.

So you are concerned about a single "possible" inode update once a day?

I'm using BackupPC to do rsync-based backups of all my systems. The "incremental" backups look only at size and timestamp changes. The less-frequent "full" backups checksum all my files. That means an extra write for every file that gets checked.

I'd love to have a version of relatime that only did the first kind of update, when ctime or mtime changed but not when 24 hours had passed.
