When kmem accounting switched from account by default to only account if flagged by __GFP_ACCOUNT, IPC mqueue and messages was left out. The production use case at hand is that mqueues should be customizable via sysctls in Docker containers in a Kubernetes cluster. This can only be safely allowed to the users of the cluster (without the risk that they can cause resource shortage on a node, influencing other users' containers) if all resources they control are bounded, i.e. accounted for.
