This involves the following modification: - Ordered extent creation This is done in process_one_page(), now PAGE_SET_ORDERED will call subpage helper to do the work. - endio functions This is done in btrfs_mark_ordered_io_finished(). - btrfs_invalidatepage() - btrfs_cleanup_ordered_extents() Use the subpage page helper, and add an extra branch to exit if the locked page have covered the full range. Now the usage of page Ordered flag for ordered extent accounting is fully subpage compatible.

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.
