Function insert_reserved_file_extent() takes a long list of parameters, which are all for btrfs_file_extent_item, even including two reserved members, encryption and other_encoding. This makes the parameter list unnecessary long for a function which only gets called twice. This patch will refactor the parameter list, by using btrfs_file_extent_item as parameter directly to hugely reduce the number of parameters. Also, since there are only two callers, one in btrfs_finish_ordered_io() which inserts file extent for ordered extent, and one __btrfs_prealloc_file_range(). These two call sites have completely different context, where ordered extent can be compressed, but will always be regular extent, while the preallocated one is never going to be compressed and always has PREALLOC type. So use two small wrapper for these two different call sites to improve readability.

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.
