+         The Kernel Memory extension for Memory Resource Controller can limit
+         the amount of memory used by kernel objects in the system. Those are
+         fundamentally different from the entities handled by the standard
+         Memory Controller, which are page-based, and can be swapped. Users of
+         the kmem extension can use it to guarantee that no group of processes
+         will ever exhaust kernel resources alone.
