This pull request is fully signed and it will be integrated in one of the next IB/CMSSW_11_2_X/master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo (and backports should be raised in the release meeting by the corresponding L2)

[smuzaffar]
