When a chunk becomes fragmented, it can end up having a large number of small allocation areas free. The free_bytes sorting of chunks leads to unnecessary checking of chunks that cannot satisfy the allocation. Switch to contig_bits sorting to prevent scanning chunks that may not be able to service the allocation request.

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.
