See my comments on 3/8; I'd much rather see us turn the existing rawio attribute into a tri-value, than to introduce a competing attribute that is mutually exclusive with rawio but has the same end goal of allowing SG_IO. This patch gets much smaller if you merely add a new value to the existing rawio enum instead of a new attribute. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
