It is strange that the you see glusterd_path_in_use() loop forever.
If I am not wrong, the inner loop checks for presence of trusted.gfid and 
trusted.glusterfs.volume-id
and should exit after that, and the outer loop performs dirname on the path 
repeatedly and dirname(3)
guarantees such an operation should return "/" eventually, which we check.
It would be great if you could provide values of local variables, "used" and 
"curdir" when you see
the looping forever. I dont have a setup to check this immediately.

thanks,
