Subject: [PATCH 06/11] target: go through normal processing for zero-length REQUEST_SENSE
Date: Fri,  7 Sep 2012 17:30:37 +0200	[thread overview]
Message-ID: <1347031842-2531-7-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1347031842-2531-1-git-send-email-pbonzini@redhat.com>

Now that spc_emulate_request_sense has been taught to process zero-length
REQUEST SENSE correctly, drop the special handling of unit attention
conditions from transport_generic_new_cmd.  However, for now REQUEST SENSE
will be the only command that goes through emulation for zero lengths.
