mainlining shenanigans

Patch series "memcg: robust enforcement of memory.high", v2. Due to the semantics of memory.high enforcement i.e. throttle the workload without oom-kill, we are trying to use it for right sizing the workloads in our production environment. However we observed the mechanism fails for some specific applications which does big chunck of allocations in a single syscall. The reason behind this failure is due to the limitation of the memory.high enforcement's current implementation. This patch series solves this issue by enforcing the memory.high synchronously if the current process has accumulated a large amount of high overcharge. This patch (of 4): The function mem_cgroup_oom returns enum which has four possible values but the caller does not care about such values and only cares if the return value is OOM_SUCCESS or not. So, remove the enum altogether and make mem_cgroup_oom returns a simple bool.

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.
