From 462b7859a07c9c2b060fa2b5b1d49f8b33706d4e Mon Sep 17 00:00:00 2001 From: Christof Schmitt Date: Tue, 19 Jun 2007 10:25:30 +0200 Subject: [SCSI] zfcp: Report FCP LUN to SCSI midlayer When reporting SCSI devices to the SCSI midlayer, use the FCP LUN as LUN reported to the SCSI layer. With this approach, zfcp does not have to create unique LUNS, and this code can be removed.
