The bnobt "find best" helper implements a simple btree walker function. This general pattern, or a subset thereof, is reused in various parts of a near mode allocation operation. For example, the bnobt left/right scans are each iterative btree walks along with the cntbt lastblock scan. Rework this function into a generic btree walker, add a couple parameters to control termination behavior from various contexts and reuse it where applicable.

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.
