Using Ganesha version 2.1.0, NFSv3 exports and clients.
We are seeing the following crash where Ganesha is trying to access parent
inode to SetPostOpAttr() and ion the crash, we see that the parent
obj_handle is NULL.
Is this a known issue, and are there any recent fices in this area? Any
help is
appreciated.
