From ded6ddc5a7b95217557fa360913d1213e12d4a6d Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Fri, 4 Aug 2017 10:36:34 +0200 Subject: scsi: clarify sense codes for LUN0 emulation The LUN0 emulation is just that, an emulation for a non-existing LUN0. So we should be returning LUN_NOT_SUPPORTED for any request coming from any other LUN. And we should be aborting unhandled commands with INVALID OPCODE, not LUN NOT SUPPORTED.
