From 0f6d64cee9c518f5d3138a90cead62fba2031074 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Wed, 31 Oct 2012 09:16:49 -0700 Subject: [PATCH] target: Implement mode page 0x1c, "Informational Exceptions" The Windows SCSI compliance test asks for this mode page, and it's easy to implement: we can just return all 0s to show we don't support any of these features.
