( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1217111?usp=email ) Change subject: CEPH: Fix crash in ceph_fsal_release ...................................................................... CEPH: Fix crash in ceph_fsal_release In "ceph_fsal_release", check is being done whether the object handle is export root. To check this op_ctx is required. In shutdown path, op_ctx is not available and hence the crash. With this fix, the check will be carried out only when op_ctx is available.
