Subject: [patch 01/12] zfcp: Reorder registration of initial SCSI device
Date: Wed, 08 Sep 2010 14:39:50 +0200	[thread overview]
Message-ID: <20100908124352.674351232@de.ibm.com> (raw)
In-Reply-To: 20100908123949.483410445@de.ibm.com

[-- Attachment #1: 700-zfcp-reorder-registration.diff --]
[-- Type: text/plain, Size: 1076 bytes --]

From: Christof Schmitt <christof.schmitt@de.ibm.com>

Make sure that the rport registration did complete and then register
SCSI device directly. Otherwise the unit_unqueue would race with the
call to zfcp_scsi_queue_unit_register.
