rbd_clone_copy_on_read ineffective with exclusive-lock
With layering+exclusive-lock feature, rbd_clone_copy_on_read does not trigger object copyups from parent image. This is due to the fact that exclusive-lock is not taken for read operations.
Note that this is not the case when journaling is enabled.
