Subject: [PATCH] target: Handle GET_EVENT_STATUS_NOTIFICATION passthrough
Date: Mon, 30 Apr 2012 16:35:13 +0100 [thread overview]
Message-ID: <1335800113-28075-1-git-send-email-stefanha@linux.vnet.ibm.com> (raw)
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.
