From e42734e270b9e5ada83188d73b733533ce11ee4a Mon Sep 17 00:00:00 2001 From: Stefan Bader Date: Fri, 15 Dec 2006 17:18:30 +0100 Subject: [PATCH] [S390] cio: css_register_subchannel race. Asynchronous probe can release memory of a subchannel before css_get_ssd_info is called. To fix this call css_get_ssd_info before registering with driver core.
