[libvirt] [libvirt-glib] [PATCH v2 1/4] GVirDomainSnapshot: Add _get_is_current

[Christophe Fergeau]

Series looks good to me apart from that naming comment in 4/4.
If someone does not like the use of gboolean *is_current as a return
value in
gboolean gvir_domain_snapshot_get_is_current(GVirDomainSnapshot *snapshot,
                                             guint flags,
                                             gboolean *is_current,
                                             GError **error) {

now would be a good time to complain ;)
