@kpedro88 could you add in the description the reason of the backport? (I guess it is for the production with fast sim)

This pull request is fully signed and it will be integrated in one of the next CMSSW_9_4_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_11_2_X is complete. This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo, @qliphy (and backports should be raised in the release meeting by the corresponding L2)

@kpedro88 I assume we need this backport for fastsim

[kpedro88]

@silviodonato yes, this is for pMSSM production.
