This callback is used to properly account delalloc extents for data inodes (ordinary file inodes and freespace v1 inodes). Those can be easily identified since they have their extent_io trees ->private_data member point to the inode. Let's exploit this fact to remove the needless indirection through extent_io_hooks and directly call the function. Also give the function a name which reflects its purpose - btrfs_set_delalloc_extent. This patch also modified test_find_delalloc so that the extent_io_tree used for testing doesn't have its ->private_data set which would have caused a crash in btrfs_set_delalloc_extent due to the btrfs_inode->root member not being initialised. The old version of the code also didn't call set_bit_hook since the extent_io ops weren't set for the inode. 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.
