Hold off setting the read-only flag in rbd_add() for an image being mapped until we have successfully probed the image. At that point we know whether it's a snapshot mapping or not, so we can set the read-only flag in that one place rather than doing so (for snapshots) in rbd_dev_mapping_set(). To do this, pass a flag to the image probe routine indicating whether we want a read-only mapping. Signed-off-by: NAlex Elder <elder@inktank.com> Reviewed-by: NJosh Durgin <josh.durgin@inktank.com>
