This patch series adds a memory.reclaim proactive reclaim interface.
The rationale behind the interface and how it works are in the first
patch.
---
Changes in V2:
- Add the interface to root as well.
- Added a selftest.
- Documented the interface as a nested-keyed interface, which makes
adding optional arguments in the future easier (see doc updates in the
first patch).
- Modified the commit message to reflect changes and add a timeout
argument as a suggested possible extension
- Return -EAGAIN if the kernel fails to reclaim the full requested
amount.
