Description Raghavendra G 2009-09-01 06:00:56 UTC 
Test setup: apache-2.2 running on booster.

The client tried to access /usr/bin/xyz, which is a symbolic link with content "../../bin/xyz". while trimming to prev-dir on encountering the second ".." from end of the path string, the path constructed would be /usr/bin/. With the path terminating in a '/', libgf_trim_to_prev_dir trims the path to "/usr/bin/" itself causing an infinite recursion in glusterfs_glh_realpath.
