tools/testing/selftests/cgroup/test_memcontrol.c contains a set of
testcases which validate expected behavior of the cgroup memory controller.
Roman Gushchin recently sent out a patchset that fixed a few issues in the
test. This patchset continues that effort by fixing a few more issues that
were causing non-deterministic failures in the suite. With this patchset,
I'm unable to reproduce any more errors after running the tests in a
continuous loop for many iterations. Before, I was able to reproduce at
least one of the errors fixed in this patchset with just one or two runs.
