Do we really need bdrv_discard and bdrv_aio_discard in the backends? I think it makes sense to have a bdrv_aio_discard() in block.h as AIO generally fits well for device models, but I would just require bdrv_co_discard for any block drivers implementing discard. > I was not sure if qcow2 could be changed to co_discard, though > I suspected yes. As discussed on IRC: Yes, it just must make sure to take s->lock. Kevin
