From 92d5193b467c68e8432d6878980621c787e735af Mon Sep 17 00:00:00 2001 From: Swen Schillig Date: Fri, 17 Apr 2009 15:08:04 +0200 Subject: [SCSI] zfcp: Dont block zfcp_wq with scan When running the scsi_scan from the zfcp workqueue and the target device does not respond, the zfcp workqueue can block until the scsi_scan hits a timeout. Move the work to the scsi host workqueue, since this one is also used for the scan from the SCSI midlayer.
