The function btrfs_punch_hole_range() is now used to replace all the file extents in a given file range with an extent described in the given struct btrfs_replace_extent_info argument. This extent can either be an existing extent that is being cloned or it can be a new extent (namely a prealloc extent). When that argument is NULL it only punches a hole (drops all the existing extents) in the file range. So rename the function to btrfs_replace_file_extents().

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.
