I don't know, maybe not. But even if it's not, there are other things (like cleaning up state) that the client will likely try to do on unmount. In the presence of delegations it could have dirty data that it's required to write back even if applications don't currently hold any open files. So I don't think we can promise umount will work without the network. --b. -- 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
