Matthew Wilcox (Oracle) 536da2a440 gfs2: Convert gfs2_end_log_write_bh() to work on a folio
gfs2_end_log_write() has to handle bios which consist of both pages
which belong to folios and pages which were allocated from a mempool and
do not belong to a folio.  It would be cleaner to have separate endio
handlers which handle each type, but it's not clear to me whether that's
even possible.

This patch is slightly forward-looking in that page_folio() cannot
currently return NULL, but it will return NULL in the future for pages
which do not belong to a folio.

This was the last user of page_has_buffers(), so remove it.

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.
