Thanks to in-house testing by Milind and Satheesaran, we now know why 
the parent directory did not have pending xattrs and why the files were 
not getting healed. You can look at 
https://bugzilla.redhat.com/show_bug.cgi?id=1801624 for more info. Once 
the fix (https://review.gluster.org/#/c/glusterfs/+/24109/) is reviewed 
and merged, I will back port it to the release branches.
