+++ This bug was initially created as a clone of Bug #1304966 +++
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.

dht: file rename must take blocking inode locks
Currently DHT takes non-blocking locks for file rename.
Due to this during parallel renames some clients fail
with EBUSY or ESTALE errors. Hence to avoid application
discontinuity file rename must take blocking inode locks.
