[Gluster-users] File (setuid) permission changes during volume heal - possible bug?

[Ravishankar N]

Hi Anirban,
Thanks for taking the time off to file the bugzilla bug report. The fix 
has been sent for review upstream (http://review.gluster.org/#/c/6862/). 
Once it is merged, I will backport it to 3.4 as well.
Regards,
Ravi
