Description of problem:
=========================
In a distribute-replicate volume, when directories with same names are created and deleted continuously on fuse and nfs mount points, after certain time the mount points hang. 



How reproducible:

test_bug_922792.sh
===================
#!/bin/bash

dir=$(dirname $(readlink -f $0))
echo 'Script in '$dir
while :
do
        mkdir -p foo$1/bar/gee
        mkdir -p foo$1/bar/gne
        mkdir -p foo$1/lna/gme
        rm -rf foo$1
done

Steps to Reproduce:
===================
1. Create a distribute-replicate volume ( 6 x 2 ). 4 storage nodes . 3 bricks on each storage node. 

2. Start the volume.

3. Create 2 fuse and 2 nfs mounts on each RHEL5.9 and RHEL6.4 clients. 

4. From all the mount points execute: "test_bug_922792.sh" 

Actual results:
===============
After sometime, fuse and nfs mount hangs. 

Expected results:
================
Fuse and nfs mount shouldn't hang.
