+++ This bug was initially created as a clone of Bug #1583018 +++

Description of problem:
Changelogs are not capturing renames and hence dependant applications like
geo-rep and glusterfind are failing.

Version-Release number of selected component (if applicable):
mainline

How reproducible:
Always

Steps to Reproduce:
1. Set distributed gluster volume
2. Enable changelog
3. Mount the volume and do rename of a file
4. Check the backend changelog for the rename record.

Actual results:
Rename is not getting recorded by changelog

Expected results:
Rename should be recorded by changelog.

Additional info:
    The changelog would journal the rename of files only when the DHT sends a
special key on the hashed subvol. The key is not being set.

This is happening only one single dht subvolume. There is a new change in DHT
which just does default rename if there is single subvol and this missed the
changelog key to be set in xdata.
