Brick , Rebalance and Mount Logs are attached

Description of problem:After creating some link files with non root user on the mount point and running rebalance , owner permissions changes for a few link files on the mount point 


Version-Release number of selected component (if applicable):


How reproducible:
quite often 

Steps to Reproduce:
1.create a distribute volume with 2 bricks

2.add another user (ABC)on the client machine and create 100 files and link files to them
for i in {1..100}; do dd if=/dev/urandom of=$i bs=1024 count=1; done
for i in {1..100}; do ln -sf $i link$i; done

3.Check the owner permissions of the file  on the mount point 
lrwxrwxrwx 1 ABC ABC    1 Jan 28  2013 link1 -> 1
lrwxrwxrwx 1 ABC ABC    2 Jan 28  2013 link10 -> 10
lrwxrwxrwx 1 ABC ABC    3 Mar 13 18:00 link100 -> 100
lrwxrwxrwx 1 ABC ABC    2 Jan 28  2013 link11 -> 11
lrwxrwxrwx 1 ABC ABC    2 Mar 13 18:00 link12 -> 12
lrwxrwxrwx 1 ABC ABC    2 Jan 28  2013 link13 -> 13
lrwxrwxrwx 1 ABC ABC    2 Mar 13 18:00 link14 -> 14
lrwxrwxrwx 1 ABC ABC    2 Jan 28  2013 link15 -> 15

4. Add another brick and initiate rebalance 

5. After rebalance is complete , check the owner permissions of the files on the mount point.

 
Actual results:

Few link files have changed the owner permission to root : 

lrwxrwxrwx 1 ABC  ABC     1 Jan 28  2013 link1 -> 1
lrwxrwxrwx 1 ABC  ABC     2 Jan 28  2013 link10 -> 10
lrwxrwxrwx 1 ABC  ABC     3 Mar 13 18:00 link100 -> 100
lrwxrwxrwx 1 ABC  ABC     2 Jan 28  2013 link11 -> 11
lrwxrwxrwx 1 ABC  ABC     2 Mar 13 18:00 link12 -> 12
lrwxrwxrwx 1 root root    2 Jan 28  2013 link13
lrwxrwxrwx 1 ABC  ABC     2 Mar 13 18:00 link14 -> 14
lrwxrwxrwx 1 ABC  ABC     2 Jan 28  2013 link15 -> 15
lrwxrwxrwx 1 ABC  ABC     2 Mar 13 18:00 link16 -> 16
lrwxrwxrwx 1 ABC  ABC     2 Jan 28  2013 link17 -> 17
lrwxrwxrwx 1 root root    2 Jan 28  2013 link18

Expected results:
The owner permissions must be retained after rebalance .
