	cgroup_disable=	[KNL] Disable a particular controller

			Format: {name of the controller(s) to disable}

	cgroup_disable=	[KNL] Disable a particular controller or optional feature

			Format: {name of the controller(s) or feature(s) to disable}

			The effects of cgroup_disable=foo are:

			- foo isn't auto-mounted if you mount all cgroups in

			  a single hierarchy

			- foo isn't visible as an individually mountable

			  subsystem

			- if foo is an optional feature then the feature is

			  disabled and corresponding cgroup files are not

			  created

			{Currently only "memory" controller deal with this and

			cut the overhead, others just disable the usage. So

			only cgroup_disable=memory is actually worthy}

			Specifying "pressure" disables per-cgroup pressure

			stall information accounting feature



	cgroup_no_v1=	[KNL] Disable cgroup controllers and named hierarchies in v1

			Format: { { controller | "all" | "named" }
