Patch series "Two minor cleanups to break_down_buddy_pages", v2. Two minor cleanups to break_down_buddy_pages. This patch (of 2): 1. We always have target in range started with next_page and full free range started with current_buddy. 2. The last split range size is 1 << low and low should be >= 0, then size >= 1. So page + size != page is always true (because size > 0). As summary, current_page will not equal to target page.

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.
