Use netfslib's read and write iteration helpers, allowing netfslib to take over the management of the page cache for 9p files and to manage local disk caching. In particular, this eliminates write_begin, write_end, writepage and all mentions of struct page and struct folio from 9p. Note that netfslib now offers the possibility of write-through caching if that is desirable for 9p: just set the NETFS_ICTX_WRITETHROUGH flag in v9inode->netfs.flags in v9fs_set_netfs_context(). Note also this is untested as I can't get ganesha.nfsd to correctly parse the config to turn on 9p support.

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.
