Replace calls to the deprecated function scatterwalk_copychunks() with memcpy_from_scatterwalk(), memcpy_to_scatterwalk(), or scatterwalk_skip() as appropriate. The new functions generally behave more as expected and eliminate the need to call scatterwalk_done() or scatterwalk_pagedone(). However, the new functions intentionally do not advance to the next sg entry right away, which would have broken chain_to_walk() which is accessing the fields of struct scatter_walk directly. To avoid this, replace chain_to_walk() with scatterwalk_get_sglist() which supports the needed functionality.

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.
