Hi Jie, Mario,
we already ran through backporting an issue with an attached CSR, so I can give you some advice:
Generally, you should create a backport JBS item for the issue with target 11-pool. From that one, you'll have to create a CSR, also with version set to 11-pool. In that CSR you can largely paste the original CSR data (as it applies).
For your case, I see that there already exists an 11-pool backport item, assigned to Fairoz Matte: https://bugs.openjdk.java.net/browse/JDK-8222896.
Maybe you and the colleagues from Oracle could cooperate on this item, at least for JDK11...? Hence, cc-ing hotspot-jfr-dev and Erik and Fairoz.
