When/Why was cldfra added to /FV3/atms_model.F90

[ericaligo-NOAA]

I'm in the process of renaming the cldfra (total 3D instantaneous cloud fraction) array to cld_amt. cldfra is declared in the physics. I made all of the model changes and I came across a compilation error related to cldfra in FV3/atmos_model.F90. I located the issue that I created in August 2020 here for adding cldfra, and I don't see that file (atmos_model.F90) as one that I modified, yet I see several instances of cldfra in it in the latest ufs-weather-model code. I don't believe this is for the inline post, I just need to know if I will need to change all instances of cldfra to cld_amt in this routine or if this is related to something else.

cldfra(i,j,k) = GFS_Data(nb)%IntDiag%cldfra(ix,k)
