Steve French f9ee31dc7f cifs: fix flushing folio regression for 6.1 backport
filemap_get_folio works differenty in 6.1 vs. later kernels
(returning NULL in 6.1 instead of an error).  Add
this minor correction which addresses the regression in the patch:
  cifs: Fix flushing, invalidation and file size with copy_file_range()

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.
