This bug having no release flag set previously, is now set with release flag 'odf‑4.15.0' to '?', and so is being proposed to be fixed at the ODF 4.15.0 release. Note that the 3 Acks (pm_ack, devel_ack, qa_ack), if any previously set while release flag was missing, have now been reset since the Acks are to be set against a release flag.

This has been fixed in recent versions of ceph. See: https://tracker.ceph.com/issues/59833

Venky, which downstream version of ceph has this fix?

The upstream backports are merged. The commits need to be ported downstream. Will push a MR for RHCS6/7.
