Comment 1 Christopher Brown 2022-04-12 08:28:48 UTC
Is this the correct 4.8 backport bug because the target release shows as 4.9.z?

Comment 2 Abu Kashem 2022-04-15 00:13:18 UTC
https://github.com/openshift/kubernetes/pull/1233 needs cherry pick approval to merge and then verified. Once verified on 4.9 we will open a new PR for 4.8. Customer is blocked and waiting in the 4.8 fix.
