I think we should fix overwrite case first. Per lkml discussion, if we
fix the overwrite case by updating the counter in file_update_time() all
the time, then the concern is this will impact other filesystems that
don't want inode versioning support.

I believe that's how leads to put this patch back (adding a mount option).

It's better to have a VFS level super block flag to indicating if the
filesystem as inode versioning support or not.

Thanks
