This involves the following modifications: - Set the order flags for __filemap_get_folio() inside prepare_one_folio() This will allow __filemap_get_folio() to create a large folio if the address space supports it. - Limit the initial @write_bytes inside copy_one_range() If the largest folio boundary splits the initial write range, there is no way we can write beyond the largest folio boundary. This is done by a simple helper calc_write_bytes(). - Release exceeding reserved space if the folio is smaller than expected Which is doing the same handling when short copy happens. All the preparations should not change the behavior when the largest folio order is 0.

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 reStructuredText 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.
