This pull request is fully signed and it will be integrated in one of the next CMSSW_7_5_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_7_6_X is complete. This pull request requires discussion in the ORP meeting before it's merged. @slava77, @davidlange6, @Degano, @smuzaffar

[slava77]

Is this change already tested/patched online?
Is the fix essential now during HI data taking?
