orangefs: Pass mapping to orangefs_writepages_work()
Remove two accesses to page->mapping by passing the mapping from
orangefs_writepages() to orangefs_writepages_callback() and then
orangefs_writepages_work().  That makes it obvious that all folios come
from the same mapping, so we can hoist the call to mapping_set_error()
outside the loop.  While I'm here, switch from write_cache_pages()
to writeback_iter() which removes an indirect function call.

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.
