Actually, when using a boot time kernel option "cgroup.memory=nokmem", all lru items are inserted to list_lru_node. But for those users who invoke list_lru_init_memcg() to initialize list_lru, list_lru_memcg_aware() returns true. And this brings unneeded operations related to memcg. To make things more convenient, let's disable memcg_aware when cgroup.memory is set to "nokmem".

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.
