Subject: [PATCH] scsi: Do not retry invalid function error
Date: Tue, 17 Oct 2017 09:10:56 +0200	[thread overview]
Message-ID: <1508224256-130260-1-git-send-email-hare@suse.de> (raw)

Hitachi USP-V returns 'Invalid function' when the internal
staging mechanism encountered an error. These errors should
not be retried on another path.
