https://github.com/ceph/ceph/pull/5765 merged upstream and shipped in upstream's v0.94.4. This will be in RHCS 1.3.2.

Verified on ceph-0.94.5-4.el7cp.x86_64

Now the objects which are promoted and evicted based on target_max_object policy.
Though always cache pool makes sure that number of objects < target_max_object but exact number of target_max_object limit is not satisfied for which I will log a new bug https://bugzilla.redhat.com/show_bug.cgi?id=1305283.
