Cache-invalidation : set to on/off depending on ganesha.enable value
Multi-Head NFS-Ganesha servers need upcall (cache-invalidation) support to notify them in case of any changes to the files in the backend. Hence, upcall xlator option "features.cache-invalidation" needs to be enabled when ganesha.enable is set to 'on'. Similarly, this feature needs to be disabled when ganesha.enable is set to 'off' Signed-off-by: Meghana Madhusudhan <mmadhusu@redhat.com> Change-Id: Ifdd1d50e48a2bd2a388f73c0b9e318c6092ac190 BUG: 1213752 Reviewed-on: http://review.gluster.org/10581 Reviewed-by: soumya k <skoduri@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com>
