Juan - here is the "official" z-stream bug. I believe all you need to do is update the gitlab commit to list *this* bug number instead of bug 2021976. I will close/duplicate that bug to here for "tracking" right after this assignment.
*** Bug 2021976 has been marked as a duplicate of this bug. ***
Adding RHEL bug 1981782 as a depends on since that's RHEL 8.6.0 bug from which we cloned to RHEL-AV bug 2024981 so that we could create the proper z-stream bug.
Can we get the qa_ack+ please, so that this can get release+?
