In fact AFS does, but it's not NFS exportable at the moment, and ceph does in a debug printk. I'd be much happier to waste a pointer in the lock stateid to avoid this inconsistant interface. And it would allow to kill find_any_fileas well.. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
