According to the code logic, the first parameter of the sub-function __get_vm_area_node() should be size instead of real_size. Then in __get_vm_area_node(), the size will be aligned, so the redundant alignment operation is deleted. The use of the real_size variable causes code redundancy, so it is removed to simplify the code. The real prefix is generally used to indicate the adjusted value of a parameter, but according to the code logic, it should indicate the original value, so it is recommended to rename it to original_align.

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.
