From 758976f9a55cb22ddc602a0690d67f9546e3e43f Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Mon, 5 Feb 2007 21:17:36 +0100 Subject: [S390] cio: Catch operand exceptions on stsch. If we have a subchannel id which has been generated via for_each_subchannel(), it might contain an invalid subchannel set id. We need to catch the ensuing operand exception by using stsch_err() instead of stsch() in all possible cases.
