	This is a simple interface to trigger memory reclaim in the

	target cgroup.



	This file accepts a string which contains the number of bytes to

	reclaim.

	This file accepts a single key, the number of bytes to reclaim.

	No nested keys are currently supported.



	Example::



	  echo "1G" > memory.reclaim



	The interface can be later extended with nested keys to

	configure the reclaim behavior. For example, specify the

	type of memory to reclaim from (anon, file, ..).



	Please note that the kernel can over or under reclaim from

	the target cgroup. If less bytes are reclaimed than the

	specified amount, -EAGAIN is returned.

	This means that the networking layer will not adapt based on

	This file also allows the user to specify the nodes to reclaim from,

	via the 'nodes=' key, for example::



	  echo "1G nodes=0,1" > memory.reclaim



	The above instructs the kernel to reclaim memory from nodes 0,1.
