Mapping of RHGS Version to RHEL Kernel

I have been looking for a mapping of the RHEL kernel that is installed with various versions of the RHGS ISO and have been unsuccessful. Currently, we have RHGS 3.0, which installed the RHEL 7.1 kernel. I am looking to upgrade the kernel to 7.2 or 7.3 and I don't know what version of RHGS to upgrade to that would include the correct kernel. I have been told that it is not recommended to upgrade the kernel from a standard RHEL repository and that I should have a separate Gluster repository configured with rpms specifically for it. Any ideas where to find a reference like this?
