            Bug ID: 1159221
           Summary: io-stats may crash the brick when loc->path is NULL in
                    some fops
           Product: GlusterFS
           Version: mainline
         Component: core

Description of problem:
Cases where loc->path is NULL, the current code in create/open/mkdir
would copy the same blindly and as a result coredump. One such case is when
resolve_loc_touchup fails to get inode_path due to loops in the inode table.
