From edf2209692769d3e461c0351553098bc017c2caf Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Wed, 30 Apr 2008 13:38:39 +0200 Subject: [S390] cio: Make isc handling more robust. Introduce an ->isc field in the subchannel to store the desired interruption subclass, since sch->schib.pmcw.isc may be overwritten by the hardware on stsch() after machine checks.
