> We encountered an exception in the use of Ozone, which was finally located because the modification time of the file was modified when Ozone was processing the file rename.
> For Linux, only the parent directory modification time is changed when renaming.
> But Ozone fs directly changes modification time of renamed files instead of its parent directory
> Linux:
> {code:bash}
> // Some comments here
> [root@mac /root/test-rename]% ls -ld ..
> drwxr-x---+ 178 root staff 5696 Oct 24 15:45 ..
> [root@mac /Users/root/test-rename]% ls -l file1
> rw-rr- 1 root staff 0 Oct 24 15:25 file1
> [root@mac /Users/root/test-rename]% mv file1 file2
> # The file modification time has not changed, its parent directory modification time has changed
> [root@mac /Users/root/test-rename]% ls -l file2
> rw-rr- 1 root staff 0 Oct 24 15:25 file2
> [root@mac /Users/root/test-rename]% ls -ld ..
