From 2470b648e17e0216922bb78c7f05b4668402459a Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Mon, 5 Mar 2007 23:36:02 +0100 Subject: [PATCH] [S390] cio: Call cancel_halt_clear even when actl == 0. The subchannel may just be status pending, even with actl == 0. We must go through the cancel_halt_clear procedure to put the subchannel into a defined state.
