From 485dd69088b6ff6cf1c1b6b2c8157c1c9846992a Mon Sep 17 00:00:00 2001 From: Sascha Silbe Date: Mon, 11 Jul 2016 13:00:36 +0200 Subject: s390x/css: copy CCW format bit from ORB to SCSW The CCW Format (F) flag of the Subchannel-Status Word (SCSW) indicates the format of the CCWs "associated with an I/O operation", i.e. the value of CCW-Format Control (F) bit of the Operation-Request Block (ORB). Copy the CCW format bit from the ORB to the SCSW so we correctly indicate the format of the CCWs to the guest.
