Within a folio/compound page, nth_page() is no longer required. Given that we call folio_test_partial_kmap()+kmap_local_page(), the code would already be problematic if the pages would span multiple folios. So let's just assume that all src pages belong to a single folio/compound page and can be iterated ordinarily. The dst page is currently always a single page, so we're not actually iterating anything.

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.
