To prepare for further bio submission changes btrfs_csum_one_bio should be able to take all it's arguments from the btrfs_bio structure. It can always use the bbio->inode already, and once the compression code is updated to set ->file_offset that one can be used unconditionally as well instead of looking at the page mapping now that btrfs doesn't allow ordered extents to span discontiguous data ranges. The only slightly tricky bit is the one_ordered flag set by the compressed writes. Replace that one with the driver private bio flag, which gets cleared before the bio is handed off to the block layer so that we don't get in the way of driver use. Note: this leaves an argument and a flag to btrfs_wq_submit_bio unused. But that whole mechanism will be removed in its current form in the next patch.

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.
