From b7e24581f3eec1d50bbdfe7bb1be6118d5bd72a3 Mon Sep 17 00:00:00 2001 From: Douglas Gilbert Date: Sat, 23 Dec 2017 12:48:11 -0500 Subject: [PATCH] scsi: scsi_debug: fix group_number mask Various cdb masks incorrectly assumed the GROUP NUMBER field was 5 bits long. It is actually 6 bits long. Correct. Also fix mask failure (in same byte) to allow DLD0 in READ(16) and WRITE(16). Signed-off-by: Douglas Gilbert Reviewed-by: Bart Van Assche Signed-off-by: Martin K.
