This function is a simple wrapper over btrfs_get_extent that returns either: a) A real extent in the passed range or b) Adjusted extent based on whether delalloc bytes are found backing up a hole. To support these semantics it doesn't need the page/pg_offset/create arguments which are passed to btrfs_get_extent in case an extent is to be created. So simplify the function by removing the unused arguments. No functional changes.

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.
