From 68d1e5f08b13132504752cad54169376739753db Mon Sep 17 00:00:00 2001 From: Stefan Weinhuber Date: Tue, 22 Sep 2009 22:58:52 +0200 Subject: [PATCH] [S390] dasd: tolerate devices that have no feature codes The DASD device driver reads the feature codes of a device during device initialization. These codes are later used to determine the availability of advanced features like PAV or High Performance FICON. Some very old devices do not support the command to read feature codes and the initialization routine fails. As the feature codes are not necessary for basic DASD operations, we can support such devices by just ignoring missing feature codes.
