The struct task_struct's in_user_fault member is not used by the cgroup v2's memory controller, so it can be put under the CONFIG_MEMCG_V1 config option. To do so, mem_cgroup_enter_user_fault() and mem_cgroup_exit_user_fault() are moved under the CONFIG_MEMCG_V1 option as well.

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 reStructuredText 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.
