[HICCUP]
Before commit 85de2be7129c ("btrfs: remove extent_map::block_start
member"), we utilized @bytenr variable inside
btrfs_extent_item_to_extent_map() to calculate block_start.
But that commit removed block_start completely, we have no need to
advance @bytenr at all.
[ENHANCEMENT]
- Rename @bytenr as @disk_bytenr
- Only declare @disk_bytenr inside the if branch
- Make @disk_bytenr const and remove the modification on it

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 reStructuredText 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.
