Matthew Wilcox (Oracle) 338f379cf7 fs: Convert vfs_dedupe_file_range_compare to folios
We still only operate on a single page of data at a time due to using
kmap().  A more complex implementation would work on each page in a folio,
but it's not clear that such a complex implementation would be worthwhile.

README

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.
