From ae4d2eb273b167dad748ea4249720319240b1ac2 Mon Sep 17 00:00:00 2001 From: Paul Durrant Date: Tue, 24 Jan 2017 14:05:47 +0000 Subject: xen-platform: add missing disk unplug option The Xen HVM unplug protocol [1] specifies a mechanism to allow guests to request unplug of 'aux' disks (which is stated to mean all IDE disks, except the primary master). This patch adds support for that unplug request. NOTE: The semantics of what happens if unplug of all disks and 'aux' disks is simultaneously requests is not clear. The patch makes that assumption that an 'all' request overrides an 'aux' request.
