From 23d805b647db6c2063a13089497615efa9deacdd Mon Sep 17 00:00:00 2001 From: Peter Oberparleiter Date: Mon, 14 Jul 2008 09:58:50 +0200 Subject: [S390] cio: introduce fcx enabled scsw format Extend the scsw data structure to the format required by fcx. Also provide helper functions for easier access to fields which are present in both the traditional as well as the modified format.
