/* We continue to block writes on degraded objects for an EC pools because
* we have to reset can_rollback_to when we get a repop without the
* transaction. If two replicas do that on sequential ops on different
* objects and then crash, other unstable objects before those two would
* also be unable to be rolled back, and would also wind up unfound.
* We can enable degraded writes on ec pools by blocking such a write
* to a peer until all previous writes have completed. For now, we
* will simply block them.
