From 260f4aeddb48b16b2f4da306f4d97d44ef102f6b Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Mon, 24 Jul 2017 12:09:36 +0200 Subject: [PATCH] scsi: scsi_transport_fc: return -EBUSY for deleted vport When trying to delete a vport via 'vport_delete' sysfs attribute we should be checking if the port is already in state VPORT_DELETING; if so there's no need to do anything.
