+          Provides a cgroup Resource Controller for HugeTLB pages.
+          When you enable this, you can put a per cgroup limit on HugeTLB usage.
+          The limit is enforced during page fault. Since HugeTLB doesn't
+          support page reclaim, enforcing the limit at page fault time implies
+          that, the application will get SIGBUS signal if it tries to access
+          HugeTLB pages beyond its limit. This requires the application to know
+          beforehand how much HugeTLB pages it would require for its use. The
+          control group is tracked in the third page lru pointer. This means
+          that we cannot use the controller with huge page less than 3 pages.
