[ Upstream commit b1f099b1cf51d553c510c6c8141c27d9ba7ea1fe ] The function in fact searches the nearest node for a given one, based on a N_ONLINE state. This is a common pattern to search for a nearest node. This patch converts numa_map_to_online_node() to numa_nearest_node() so that others won't need to opencode the logic.

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.
