The variable @bio_offset was introduced in commit 7ffd27e378d2 ("btrfs:
pass bio_offset to check_data_csum() directly"), when we are still using
the same endio function for both data and metadata.
Later we had several changes to data and metadata endio functions:
- Data verification is handled by btrfs bio layer
- Split data and metadata endio paths
Now for data path we no longer do any verification in
end_bbio_data_read(), as the verification is handled by btrfs bio layer
already.
Thus there is no need for such bio_offset variable.

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.
