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
reclaim induced by memory.reclaim.
- 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.
