If a bio gets split, it needs to have a proper file_offset for checksum validation and repair to work properly. Based on feedback from Josef, commit852eee62d3("btrfs: allow btrfs_submit_bio to split bios") skipped this adjustment for ONE_ORDERED bios. But if we actually ever need to split a ONE_ORDERED read bio, this will lead to a wrong file offset in the repair code. Right now the only user of the file_offset is logging of an error message so this is mostly harmless, but the wrong offset might be more problematic for additional users in the future.

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.
