config CGROUP_FREEZER

	bool "Freezer cgroup subsystem"

	bool "Freezer controller"

	help

	  Provides a way to freeze and unfreeze all tasks in a

	  cgroup.

config CGROUP_PIDS

	bool "PIDs cgroup subsystem"

	bool "PIDs controller"

	help

	  Provides enforcement of process number limits in the scope of a

	  cgroup. Any attempt to fork more processes than is allowed in the

	  attach to a cgroup.

config CGROUP_DEVICE

config PAGE_COUNTER

       bool

config MEMCG

	bool "Memory Resource Controller for Control Groups"

	bool "Memory controller"

	select PAGE_COUNTER

	select EVENTFD

	help

	  Provides a memory resource controller that manages both anonymous

	  memory and page cache. (See Documentation/cgroups/memory.txt)

	  Provides control over the memory footprint of tasks in a cgroup.

config MEMCG_SWAP

	bool "Memory Resource Controller Swap Extension"

	bool "Swap controller"

	depends on MEMCG && SWAP

	help

	  Add swap management feature to memory resource controller. When you

	  enable this, you can limit mem+swap usage per cgroup. In other words,

	  when you disable this, memory resource controller has no cares to

	  usage of swap...a process can exhaust all of the swap. This extension

	  is useful when you want to avoid exhaustion swap but this itself

	  adds more overheads and consumes memory for remembering information.

	  Especially if you use 32bit system or small memory system, please

	  be careful about enabling this. When memory resource controller

	  is disabled by boot option, this will be automatically disabled and

	  there will be no overhead from this. Even when you set this config=y,

	  if boot option "swapaccount=0" is set, swap will not be accounted.

	  Now, memory usage of swap_cgroup is 2 bytes per entry. If swap page

	  size is 4096bytes, 512k per 1Gbytes of swap.

	  Provides control over the swap space consumed by tasks in a cgroup.

config MEMCG_SWAP_ENABLED

config CGROUP_HUGETLB

	bool "HugeTLB Resource Controller for Control Groups"

	bool "HugeTLB controller"

	depends on HUGETLB_PAGE

	select PAGE_COUNTER

	default n

	help

	  Provides a cgroup Resource Controller for HugeTLB pages.

	  Provides a cgroup 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 we cannot use the controller with huge page less than 3 pages.

config CGROUP_PERF

	bool "Enable perf_event per-cpu per-container group (cgroup) monitoring"

	bool "Perf controller"

	depends on PERF_EVENTS && CGROUPS
