3.2.75-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Jeff Layton <jlayton@xxxxxxxxxxxxxxx> commit c812012f9ca7cf89c9e1a1cd512e6c3b5be04b85 upstream. If we pass in an empty nfs_fattr struct to nfs_update_inode, it will (correctly) not update any of the attributes, but it then clears the NFS_INO_INVALID_ATTR flag, which indicates that the attributes are up to date. Don't clear the flag if the fattr struct has no valid attrs to apply.
