Subject: [PATCH 4/4] zfcp: fix: avoid race between fc_remote_port_add and scsi_add_device
Date: Sat, 11 Feb 2006 01:43:55 +0100 [thread overview]
Message-ID: <20060211004355.GA17355@lion28.ibm.com> (raw)
Flush workqueue of a scsi host after a remote port for that host
is registered at the fc transport class. Otherwise immediate
registration of a scsi device on that host is racy.
