          Elevating this to a 2.4.0 blocker. If we don't get this patch landed, we will be in for a world of problems when we want to add a new DLM flag, and since 2.4.0 is expected to be in use for a longer time, it needs to be fixed for this release if we hope to even be able to use these flags again.
