[NFS-Ganesha-Devel] Back port suggestions to v2.6

Hi, As discussed with Daniel on one of the issues on github, here are some candidates for back porting to v2.6 for the final 2.6 release. Explicitly revert the following changes on V2.6-stable: 57908cc GLUSTER: Use telldir result from previous dirent as cookie e52b213 VFS: Use d_off from previous dirent as cookie Back port following changes to V2.6-stable: 660f330 FSAL_MDCACHE: avoid assertion due to wrong check fb5f604 Fix leaks related to CIDR clients 10e4b26 AUTH - Return correct result 1b65dbb Free group name string properly in proc_export() faa9745 Allow exports to be referral points in FSAL_VFS fab810d Remove unexported export on DBUS unexport. I have tried to pick independent changes so that we do not have to back port a chain of commits. Please let me know if the list of commits is good. Thanks, Sriram
