fuse: hook into iomap for invalidating and checking partial uptodateness
Hook into iomap_invalidate_folio() so that if the entire folio is being
invalidated during truncation, the dirty state is cleared and the folio
doesn't get written back. As well the folio's corresponding ifs struct
will get freed.

Hook into iomap_is_partially_uptodate() since iomap tracks uptodateness
granularly when it does buffered writes.

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.
