This pull request is fully signed and it will be integrated in one of the next CMSSW_7_5_X IBs unless changes (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @Degano, @smuzaffar

Since data taking (and corresponding validation) is actually done with 74X, does it exist (or do you foresee) a 74X counterpart of this pull request?

[BetterWang]

Hi @perrotta , There is a back port #9382 of this fix and PR #9022.
My understanding would be the heavy ion data taking release will be 75X. Thanks.
