--- Doc Text *updated* ---
Since directory operations are processed by multiple workers of geo-replication. If symlink is created and renamed followed by directory creation with same name as the original symlink file. The race causes out of order syncing causing directory to be synced first failing to sync the rename of the symlink.

Geo-rep sometimes fails to sync the rename of symlink.

Example I/O pattern:
 1. touch file1 
 2. ln -s "./file1" sym_400
 3. mv sym_400 renamed_sym_400 
 4. mkdir sym_400 

The file 'renamed_sym_400' failed to sync to slave 

While processing out of order RENAME, if name already exists use gfid to check the identity of the file. Using which, such renames can be properly synced.

Geo-rep syncs renames of symlink
