From: "Darrick J. Wong" <darrick.wong@oracle.com> commit5ffce3cc22upstream. Commit5833112df7tried to make it so that a remap operation would force the log out to disk if the filesystem is mounted with mandatory synchronous writes. Unfortunately, that commit failed to handle the case where the inode or the file descriptor require mandatory synchronous writes. Refactor the check into into a helper that will look for all three conditions, and now we can treat reflink just like any other synchronous write. Fixes:5833112df7("xfs: reflink should force the log out if mounted with wsync") Signed-off-by: Darrick J.

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.
