From 568e1f6524b06ff113cebf5711832ca95d37259f Mon Sep 17 00:00:00 2001 From: Joern Engel Date: Wed, 22 Jul 2015 15:01:36 -0700 Subject: target: improve unsupported opcode message Make the warning about unsupported SCSI opcode more useful: - Add in the initiator name so we know who's sending it. - Print the warning even for opcodes that spc_parse_cdb() knows about but that we don't handle.
