This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @davidlange6, @slava77, @smuzaffar, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)

[rekovic]

@fabiocos
94X version is https://github.com/cms-sw/cmssw/pull//22520

[slava77]

@fabiocos
please clarify the situation with this PR.
FWIW, it is technical and should be OK for 10_1_X.
Also, it should resolve potential issues with reading prescales that were so far seen only in 80XLegacy but apparently can happen elsewhere.

[fabiocos]

@slava77 this is effectively a fix to my mind, so I see no reasons not to merge it.
