I'm not an expert, but honestly the current behavior sound more correct
than the proposed behavior.  What's the issue specifically so we can
understand it better?  Also bug fixes need a Fixes tag.

The patch has a number of style issues and the existing_file_inode
allocation is not always freed so those memory leaks would need to be
fixed.  For the style issues run ./scripts/checkpatch.pl on your patch.
