Description of problem:
DHT takes non-blocking locks while renaming files. During parallel renames and
parallel rebalance and rename clients might fail with EBUSY or ESTALE errors.
Hence to avoid application discontinuity renaming of files must take blocking
locks.

Hence it is better to take blocking locks for renaming files.
