We have two main methods to find free extents inside a block group: 1) clustered allocation 2) unclustered allocation This patch will extract the clustered allocation into find_free_extent_clustered() to make it a little easier to read. Instead of jumping between different labels in find_free_extent(), the helper function will use return value to indicate different behavior.

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.
