From ed0b2144c50b03ed926aa1c582178abb661325e2 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Mon, 30 Apr 2012 16:35:13 +0100 Subject: [PATCH] target: Handle GET_EVENT_STATUS_NOTIFICATION passthrough The SCSI MMC GET_EVENT_STATUS_NOTIFICATION command can be used to find out about media change, among other things. This patch adds it to the command sequencer so that PSCSI CD-ROM passthrough works with modern Linux guests that issue this command.
