vboxsf: Convert to writepages
If we add a migrate_folio operation, we can convert the writepage
operation to writepages.  Further, this lets us optimise by using
the same write handle for multiple folios.  The large folio support here
is illusory; we would need to kmap each page in turn for proper support.
But we do remove a few hidden calls to compound_head().

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.
