Currently, direct I/O has its own versions of bio_readpage_error() and btrfs_check_repairable() (dio_read_error() and btrfs_check_dio_repairable(), respectively). The main difference is that the direct I/O version doesn't do read validation. The rework of direct I/O repair makes it possible to do validation, so we can get rid of btrfs_check_dio_repairable() and combine bio_readpage_error() and dio_read_error() into a new helper, btrfs_submit_read_repair().

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.
