Let's prepare our page onlining code for subblock size smaller than MAX_ORDER - 1: we'll get called for a MAX_ORDER - 1 page but might have some subblocks in the range plugged and some unplugged. In that case, fallback to subblock granularity to properly only expose the plugged parts to the buddy.

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.
