From c2b1449bd1fd73103ed5ff1a28d8f7cbc8a01b52 Mon Sep 17 00:00:00 2001 From: Cornelia Huck <cornelia.huck@de.ibm.com> Date: Fri, 27 Oct 2006 12:39:17 +0200 Subject: [PATCH] [S390] cio: css_probe_device() must be called enabled. Move css_probe_device() behind giving up the lock for the old subchannel in css_evaluate_known_subchannel() so we aren't disabled when we call it.
