Subject: [PATCH 16/27] scsi: consolidate opcode lookup in scsi_opcode_sa_name()
Date: Mon, 20 Oct 2014 08:52:19 +0200 [thread overview]
Message-ID: <1413787950-14659-17-git-send-email-hare@suse.de> (raw)
In-Reply-To: <1413787950-14659-1-git-send-email-hare@suse.de>
Consolidate the CDB opcode lookup in scsi_opcode_sa_name(),
so that we don't have to call several functions to figure
out the CDB opcode string.
