Subject: [PATCH 6/8] blockdev-test: add test case for drive_add duplicate IDs

RH-Author: Stefan Hajnoczi <stefanha@redhat.com>

Patchwork-id: 56260
O-Subject: [RHEL7 qemu-kvm PATCH 6/8] blockdev-test: add test case for drive_add duplicate IDs
Bugzilla: 1003773
RH-Acked-by: Paolo Bonzini <pbonzini@redhat.com>
RH-Acked-by: Jeffrey Cody <jcody@redhat.com>
RH-Acked-by: Markus Armbruster <armbru@redhat.com>

The following should work:

  (qemu) drive_add if=none,id=drive0
  (qemu) drive_del drive0
  (qemu) drive_add if=none,id=drive0

Previous versions of QEMU produced a duplicate ID error because
drive_add leaked the options.
