From 77fd9494bce3188c20d82e45464ed9b1be83bf98 Mon Sep 17 00:00:00 2001 From: Christof Schmitt Date: Tue, 4 Nov 2008 16:35:10 +0100 Subject: [SCSI] zfcp: Wait for port scan to complete when setting adapter online Attaching a unit immediately after setting the adapter online should be possible. The problem right now is that the port_scan runs from a workqueue and has not finished when the set_online call returns and the sysfs structures for the ports are not available yet. Fix that by waiting for the port scan to complete.
