Thomas, This is to confirm that the internal testing has completed and all the tests passed. So, yes, we can push that into 19.05-rc1. We will have another patch out for the smp barriers as well. That is still being tested. We will also need to get these patches into 18.11 and higher releases. We will work with others to get that done. Thanks Pradeep pradeep@us.ibm.com
