Patch series "mm: memcg kselftests fixes".
This patch (of 4):
Commit 9852ae3fe5 ("mm, memcg: consider subtrees in memory.events") made
memory.events recursive: all events are propagated upwards by the tree.
It was a change in semantics.
It broke the oom group leaf events test: it assumes that after an OOM the
oom_kill counter is zero on parent's level.
Let's adjust the test: it should have similar expectations for the child
and parent levels.
The test passes after this fix.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
